Data typically requires context or meaning in order to be of value. In an applied sense the context is often implemented in the form of a data model. Contemporary manufacturing environments rely on the use of data models both throughout their automation landscape as well as within most layers of business operations. Industry 4.0 (with a projected market spend of over US$150 billion by around 2026) relies heavily on the use of data models. The scale, complexity and level of integration of data models is set to increase markedly over the next phases of migration towards Industry 4.0.However the nature, location(s) and significance of data models are not always understood by many of the stakeholders within the enterprise. This can lead to decisions around system architecture, ownership and accountability that result in sub-optimal outcomes for the enterprise.This paper clarifies the nature and characteristics of data models in the manufacturing enterprise, providing a context and understanding for stakeholders and decision makers.
数据通常需要上下文或含义才能有价值。在应用意义上,上下文通常以数据模型的形式实现。现代制造环境依赖于数据模型的使用,无论是在整个自动化环境中,还是在大多数业务操作层中。工业4.0(预计到2026年左右市场支出将超过1500亿美元)严重依赖于数据模型的使用。在向工业4.0迁移的下一个阶段,数据模型的规模、复杂性和集成水平将显著提高。然而,数据模型的性质、位置和重要性并不总是被企业中的许多涉众所理解。这可能导致围绕系统架构、所有权和责任的决策,从而导致企业的次优结果。本文阐明了制造企业中数据模型的性质和特征,为利益相关者和决策者提供了一个背景和理解。

In this paper, an Adaptive Indirect Inverse Control (IAIC) methodology based on the Finite Impulse Response (FIR) Filter is proposed, such that the controller is represented by an adaptive FIR Filter. The estimate of the weights vector of FIR Filter can be performed through an adaptive algorithm based on stochastic gradient descent, such that the performance of IAIC is influenced by the performance of update of the weights vector, in terms of convergence speed and steady-state Mean Square Error (MSE), that, consequently, is influenced by the step size of an adaptive algorithm. Aiming to present a proposal to solve this problem, a new version of NLMS algorithm is proposed, with the adapted step size through Mamdani Fuzzy Inference System (MFIS). The proposed algorithm was evaluated in the IAIC syhnthesis and applied in non-minimum phase plant, in the presence of a sinusoidal disturbance signal added to the control signal.
本文提出了一种基于有限脉冲响应(FIR)滤波器的自适应间接逆控制(IAIC)方法,使控制器由自适应FIR滤波器表示。FIR滤波器权向量的估计可以通过基于随机梯度下降的自适应算法来实现,因此IAIC的性能受到权向量更新性能的影响,在收敛速度和稳态均方误差(MSE)方面,从而受到自适应算法步长的影响。为了解决这一问题,本文提出了一种新的NLMS算法,该算法通过Mamdani模糊推理系统(MFIS)调整步长。在IAIC合成中对该算法进行了验证,并将其应用于控制信号中加入正弦干扰信号的非最小相位对象。

Monitoring of Froth Flotation with Transfer Learning and Principal Component Models* 基于迁移学习和主成分模型的泡沫浮选监测*

Xiu Liu, C. Aldrich
Froth flotation is widely used in mineral processing to separate valuable mineral ores from gangue or waste material. As such, improved monitoring and control of flotation systems can have a significant impact on mineral processing efficiency. To this end, videographic monitoring of flotation cells is well established commercially to enable decision support in plant operations, but its application in automated monitoring and control is still emerging. In this paper, the incorporation of transfer learning with deep convolutional neural networks in traditional multivariate process monitoring is considered. It is shown that despite their high dimensionality, froth image features extracted with AlexNet provides better performance than achievable with traditional multivariate image methods.
泡沫浮选在选矿中广泛应用于从脉石或废料中分离有价矿物。因此,改善浮选系统的监测和控制可以对选矿效率产生重大影响。为此目的,浮选池的录像监测已在商业上得到很好的建立,以便在工厂作业中支持决策,但其在自动化监测和控制方面的应用仍在出现。本文将迁移学习与深度卷积神经网络结合到传统的多变量过程监测中。研究表明,尽管泡沫图像特征具有高维数,但用AlexNet提取的泡沫图像特征比传统的多元图像方法提供了更好的性能。

Controllers for distributing mobile agents to cover a desired region have become popular in the motion-coordination literature, including numerous variations on the problem. In most cases, coverage controllers target asymptotic stability, in the Lyapunov sense, to the centroids of Voronoi cells. The popular cost function used exhibits multiple local minima and maxima, and the problem of computing the global minimum is known to be NP-hard. This paper provides explicit definitions for the rate of convergence of the network utilising a distributed coverage controller. In addition, under an assumption of strong local convexity, we provide an alternate stability proof that shows the controller exhibits exponential stability to local minima. An example is provided to illustrate conditions which strong local convexity holds.

This paper provides a comparative study of nonlinear motion control techniques for a generic BB2 underwater vehicle. Two different nonlinear controllers, state feedback linearisation control and Nonlinear Model Predictive Control (NMPC), are developed to track defined manoeuvres of the vehicle. The highly nonlinear and coupled dynamics, system uncertainties and environmental disturbances of underwater vehicles make their control design difficult. This paper attempts to compensate these nonlinearities by applying the proposed nonlinear controllers. The primary objective of the proposed nonlinear controllers is to track the desired states of the BB2 vehicle effectively. The effectiveness of these proposed controllers are examined through numerical simulations. The simulation results of the proposed controllers are then compared and discussed. The simulation results show the effectiveness of the proposed controllers, which are essential for the safe operation of the BB2 underwater vehicle.

Unmanned Aerial Vehicles (UAVs) have become the necessary tools for a wide range of activities including but not limited to real-time monitoring, surveillance, border patrolling, search and rescue, civilian, scientific and military missions, etc. Their advantage is unprecedented and irreplaceable especially in environments dangerous to humans, for example in radiation or pollution exposed areas. A method for occlusion-aware UAV path planning is presented in this paper, which ensures every point on the target ground area can be seen at least once in a complete surveillance circle. Besides, the geometrically complex environments with occlusions are considered in our research. Compared with many existing methods, we decompose this problem into a waypoint determination problem and an instance of the traveling salesman problem.

In this work we propose to explore and optimise a novel concept in adaptive optics wavefront sensing. The notion being investigated is that of super-resolution, which is aimed at increasing spatial resolution in tomographic adaptive optics by introducing diversity in the alignment of different wavefront sensors. The optimisation of super-resolution requires efficient computation of the wavefront estimation error. A model of the wavefront sensor compatible with super-resolution is proposed in this paper, together with a suitable cost function to optimise the super-resolution geometry. We provide initial optimisation results verified by end-to-end simulations. In future work we will investigate the parallelisation of the optimisation routine, and alternative optimisation methods.
在这项工作中,我们提出探索和优化自适应光学波前传感的新概念。正在研究的概念是超分辨率,其目的是通过引入不同波前传感器的多样性来提高层析自适应光学的空间分辨率。超分辨率的优化需要有效地计算波前估计误差。本文提出了一种兼容超分辨率的波前传感器模型,并提出了合适的成本函数来优化超分辨率几何结构。我们提供了通过端到端模拟验证的初始优化结果。在未来的工作中,我们将研究优化例程的并行化和替代优化方法。

This paper describes the method for reconfiguring formations when some UAVs fail in a formation flight. We proposed fault detection using correlation coefficient and formation reconfiguration by applying the optimal allocation problem in this method. The correlation coefficient can detect faults by examining the similarity between the commanded value of the control input and the actual input. The optimal assignment problem can ensure a one-to-one assignment of UAVs to new target positions and minimize the total distance moved during the reconfiguration. Numerical simulation is performed to confirm the effectiveness of the proposed method for the formation flight of fixed-wing UAVs.

General Type-2 Fuzzy Logic Systems Using Shadowed Sets: A New Paradigm Towards Fault-Tolerant Control 利用阴影集的一般2型模糊逻辑系统:一种容错控制的新范式
Pub Date : 2021-11-25 DOI: 10.1109/anzcc53563.2021.9628361

Fuzzy Inference Systems (FIS) are now widely employed to regulate a wide range of safety-critical engineering systems. The main reason for this is that FIS may be created using expert human knowledge. Furthermore, with the introduction of Type-2 Fuzzy Logic, the ability to handle uncertainty offers an alluring improvement for fault-tolerant abilities in fault-tolerant control methods, and, in fact, recent studies have shown that the use of Interval Type-2 Fuzzy Inference Systems (IT2 FIS) provides better results than Type-1 Fuzzy Inference Systems (T1 FIS).The current research intends to suggest a novel strategy employing Shadowed Type-2 Fuzzy Inference System (ST2 FIS) for significant features in fault-tolerant capability in the Passive Fault-Tolerant Control (PFTC) method based on the performance increase shown by IT2 FIS. The ST2 FIS is based on the ideas of Shadowed Fuzzy Sets and is an approximation of General Type-2 Fuzzy Inference Systems (GT2 FIS). The fundamental rationale for utilising ST2 FIS instead of GT2 FIS is that the computational cost of GT2 FIS is too high for this application. The simulation results for the FTC using IT2 FIS and FTC using ST2 FIS for Coupled Conical Tank Level Control (CCTLC) system with 30 % and 40% loss of effectiveness in the main actuator are presented in this study. In addition, the article compares the proposed FTC approach using ST2 FIS to FTC using IT2 FIS in terms of fault-recovery time.
模糊推理系统(FIS)现在被广泛应用于调节各种安全关键工程系统。这样做的主要原因是FIS可以使用人类的专业知识来创建。此外,随着2型模糊逻辑的引入,处理不确定性的能力为容错控制方法中的容错能力提供了诱人的改进,事实上,最近的研究表明,使用区间2型模糊推理系统(IT2 FIS)比1型模糊推理系统(T1 FIS)提供了更好的结果。在被动容错控制(PFTC)方法中,基于阴影型2模糊推理系统(ST2 FIS)所显示的性能提升,本研究提出了一种基于阴影型2模糊推理系统(ST2 FIS)的容错能力显著特点的新策略。ST2模糊推理系统基于阴影模糊集的思想,是一般2型模糊推理系统(GT2 FIS)的近似。使用ST2 FIS而不是GT2 FIS的基本原理是GT2 FIS的计算成本太高。本文给出了FTC使用IT2 FIS和FTC使用ST2 FIS对耦合锥形罐液位控制(CCTLC)系统的仿真结果,其中主要执行器的有效性损失分别为30%和40%。此外,在故障恢复时间方面,本文比较了使用ST2 FIS的拟议FTC方法与使用IT2 FIS的FTC方法。

In control systems, uncertain delays are unavoidable in communication channels. Further, the requirement to track and reject periodic signals has many applications in engineering. However, in most cases disturbances to be compensated are not just periodic but can also be aperiodic. This paper presents a novel Repetitive controller based disturbance observer (RCDOB) to reject both periodic and aperiodic disturbances while being able to track periodic signals in systems with uncertain communication delays.
在控制系统中,通信信道中的不确定性延迟是不可避免的。此外,跟踪和抑制周期信号的要求在工程中有许多应用。然而,在大多数情况下,要补偿的干扰不仅是周期性的,也可以是非周期性的。本文提出了一种新的基于重复控制器的干扰观测器(RCDOB),它既能抑制周期和非周期干扰,又能在具有不确定通信延迟的系统中跟踪周期信号。
