Particle size distribution (PSD) control is very complicated to realize due to the absence of effective measuring methods for PSD. In order to solve this problem, an iteration learning control strategy based on the moment generation network model is proposed. The tracking control of PSD which cannot be measured online is converted into the measurable moment control. There are two steps to develop the control strategy. Firstly, a moment generation network is built to construct the relationship between the moment and process measurements. Then an iteration learning control strategy is designed to drive the process to achieve a target PSD according to the repetitive nature of the process. The cobalt oxalate synthesis process was selected to test the performance of the control strategy. The experimental results demonstrated that the approach had a strong ability in convergence and resisting disturbance.

Fault detection and diagnosis is an important issue for mobile robots, especially for the case that the dynamics of fault models are unknown, where the samples of fault models are difficult to obtain. Support vector data description (SVDD) is an useful tool for model construction based only on one class of samples. This paper presents a fault detection method for mobile robots internal sensors based on SVDD. It assumes that only the samples from the normal model are available. The presented method firstly builds an compact hypersphere for these normal samples based on SVDD, then a new test data is validated with the obtained hypersphere. Simulation results of mobile robot fault detection show the accuracy of the method.

In order to solve the problems of decision-making on inspection intervals of hidden functional failures for electronic equipment, a mathematical model was developed using probability and stochastic process theories. The maintenance costs were modeled by using the concept of delay time and considering the imperfect inspections. The optimal intervals of inspections were obtained by minimizing expected maintenance cost per unit time. And then, the corresponding optimization algorithm was presented, and an example was provided to show the optimization process and rectify the effectiveness of the algorithm.

There are a large quantity of control loops in an Networked Control Systems (NCSs) and a control loop consists of two message tasks and a control task which are interactional and interrelated and run on different kinds of resources. For asynchronous NCS, a new algorithm is presented in this paper to schedule these tasks. In our algorithm, the precedence constraints among the subtasks of a loop can be met by controlling their start times and finish times. And the second message tasks of all the loop tasks are arranged according to backward non-preemptive EDF. The first message tasks of all loop tasks are scheduled according to non-preemptive EDF. The algorithm for assigning control tasks to processors is designed and control tasks are scheduled according to their available times. The experiment results show that the algorithm can schedule message tasks and control tasks effectively.

In order to improve the traditional Particle Swarm Optimization (PSO) algorithm's speed and optimization ability, this paper proposes a new algorithm based on CUDA (Compute Unified Device Architecture) technology which employs the two level PSO, the bottom level PSO and the top level PSO. And in the bottom level, the particles are divided into N groups, each of which will run the PSO and send the best particle to the top level individually to achieve better convergency. And the algorithm applys the CUDA threads to run the above PSO at different levels parallel to accelerate the algorithm speed. The simulation results show that the performance of the algorithm the paper provided is better than that of the traditional PSO.

This paper studies the leader-following consensus problem of general multi-agent systems, in which dynamics of all agents are affected by unknown nonlinear dynamics. By parameterizing the unknown nonlinear terms, a distributed adaptive consensus algorithm is proposed for each follower agent. With a modified labeling rule, consensus analysis is conducted for the multi-agent systems with jointly connected topology based on algebraic graph theory and Lyapunov theory. Finally, a simulation example is provided to validate the theoretical results.

Penetration Rate is an important parameter of hard rock tunnel boring machine (TBM) in tunneling project. The prediction accuracy of Penetration Rate has great effect on the successful accomplishment of tunneling project. The aim of this paper is to predict the penetration rate and rank the importance of rock mass properties via Random Forests algorithm. Random Forests is a high accuracy regression algorithm, which is not prone to over fitting and has good tolerance to outliers and noise. A database including actual, measured penetration rates and several rock mass properties are established by using the data collected from a real tunnel project. Based on the database, we use random forests algorithm to model the penetration rate of the tunnel project. The simulation results show that the random forest based prediction model has better predictive accuracy and can sort the features of rock mass properties (UCS, BTS, PSI, DPW and alpha) by the importance.

This paper presents a system modeling method for an multi-stage operational amplifier circuit based on the step response experiment. By taking an step voltage signal as the input, the measure data are collected for estimating the system parameters. By defining and minimizing an output error criterion function, a Newton iterative estimation algorithm is derived. In order to show the accuracy of the estimated circuit model, we use a proportional integral controller and construct a closed-loop operational amplifier circuit in terms of the estimated circuit model. Moreover, we take a step experiment to test the tracking performance of the operational amplifier circuit. The simulation results indicate that the proposed method can generate the parameter estimates of the multi-stage operational amplifier circuit system.
