Enforcing Data-Aware Business Processes Using Execution Path-Oriented Strategies 使用面向执行路径的策略强制执行数据感知业务流程

Since the data-aware business process usually covers the control flow and data flow, and both of them have a direct impact on its execution, it is challenging to ensure its correctness. In this article, we propose a novel correctness enforcement approach for the data-aware business the processes. Given a data-aware business process, this approach first relies on the notion of the execution paths to capture all the parts of it that can be executed correctly. More specifically, it first splits the data-aware business process into a set of the execution paths, and then presents the notion of well-formedness to determine whether each execution path is correct. Based on these captured correct execution paths, an execution path-oriented strategy is generated, which is nonintrusive, and can enforce it to follow one of its correct execution paths during each execution, thereby realizing its correct execution. This approach is evaluated using the extensive experiments, which shows that it is effective and efficient, as well as scalable in practice.
由于数据感知业务流程通常包括控制流和数据流,而这两种流都会对流程的执行产生直接影响,因此确保流程的正确性是一项挑战。在本文中,我们为数据感知业务流程提出了一种新的正确性执行方法。给定一个数据感知业务流程,这种方法首先依赖于执行路径的概念来捕捉流程中可以正确执行的所有部分。更具体地说,它首先将数据感知业务流程拆分成一组执行路径,然后提出良好形成性概念,以确定每条执行路径是否正确。根据这些捕捉到的正确执行路径,生成一个面向执行路径的策略,该策略是非侵入式的,可以在每次执行过程中强制其遵循正确的执行路径之一,从而实现正确的执行。我们通过大量实验对这种方法进行了评估,结果表明这种方法既有效又高效,在实践中还具有可扩展性。

Event-Triggered Heading Control of an Energy-Efficient Underwater Gliding Robot 高能效水下滑行机器人的事件触发式航向控制

An energy-efficient event-triggered heading control system (ETHCS) is proposed for an underwater gliding robot. The robot steers by adjusting the position of an internal axially moving mass, rather than with the actuators commonly used in traditional underwater vehicles. Based on the dynamic model, an energy-efficient ETHCS framework, which includes three linear velocity observers and an event-triggered high-order backstepping heading controller, is established. The three linear state observers estimate the horizontal and angular velocities of the robot using depth and attitude angles measured by a depth sensor and an attitude and heading reference system (AHRS). The controller is developed by using the dynamic surface control technique to avoid differentiating virtual control laws. A neural network is used to approximate recursive model uncertainties and disturbances. Relative threshold event-triggering conditions are designed to reduce the frequency of actuator action and the controller working time and to improve the energy-saving efficiency. The simulation and sea trial results show the effectiveness of the proposed control system.
为水下滑行机器人提出了一种节能的事件触发航向控制系统(ETHCS)。该机器人通过调整内部轴向移动质量块的位置来转向,而不是使用传统水下航行器中常用的致动器。在动态模型的基础上,建立了一个高能效的 ETHCS 框架,其中包括三个线性速度观测器和一个事件触发的高阶反步航向控制器。三个线性状态观测器利用深度传感器和姿态与航向参考系统(AHRS)测量的深度和姿态角来估计机器人的水平速度和角速度。控制器的开发采用了动态表面控制技术,以避免区分虚拟控制律。神经网络用于近似递归模型不确定性和干扰。设计了相对阈值事件触发条件,以减少执行器动作频率和控制器工作时间,提高节能效率。仿真和海上试验结果表明了所提控制系统的有效性。

Finite-Time Fuzzy Preassigned-Performance Control for Nonlinear Systems Subject to Asymmetric State-Constraints Based on Command Filter 基于指令滤波器的受非对称状态约束的非线性系统的有限时间模糊预分配性能控制

This article presents a novel command-filter-based finite-time fuzzy preassigned performance adaptive control approach for nonlinear systems with exogenous disturbances and asymmetric time-varying constraints. Combining the asymmetric barrier Lyapunov function (ABLF) with preassigned performance control (PPC), it is ensured that the state $x_{1}$ satisfies the required asymmetric time-varying state constraints (ATSCs), and the system output y can track the desired signal with achieving preassigned performance indices (PPIs). The command-filter-based control design not only circumvents the computing complexity in the backstepping but also reduces the conservativeness of the assumption regarding the desired signal and the time-varying asymmetric constraints. Additionally, the nonlinear disturbance observer method (NDOM) is employed to effectively estimate unknown exogenous disturbances and enhance the robustness of the closed-loop system. Through rigorous theoretical analysis, the proposed finite-time command filter-based control method effectively ensures that all variables are bounded within a finite time. The practicality and feasibility of the proposed approach are further validated by simulation results.
本文针对具有外生干扰和非对称时变约束的非线性系统,提出了一种新颖的基于指令滤波的有限时间模糊预分配性能自适应控制方法。将非对称障碍李亚普诺夫函数(ABLF)与预分配性能控制(PPC)相结合,可确保状态 $x_{1}$ 满足所需的非对称时变状态约束(ATSC),并且系统输出 y 可以在实现预分配性能指标(PPI)的情况下跟踪所需的信号。基于指令滤波器的控制设计不仅规避了反步法的计算复杂性,还降低了对期望信号和非对称时变约束条件假设的保守性。此外,还采用了非线性扰动观测器方法(NDOM)来有效估计未知的外生扰动,增强闭环系统的鲁棒性。通过严格的理论分析,所提出的基于有限时间指令滤波器的控制方法能有效确保所有变量在有限时间内都是有界的。仿真结果进一步验证了所提方法的实用性和可行性。
