基于时间窗口的网络控制系统调度算法

由于网络控制系统中各个控制设备共享物理传输介质,造成了控制设备争用总线的问题,从而引起了控制数据传输的延时,而反馈控制系统的稳定性能由环延时决定,需要研究一种调度算法对网络中消息的传输进行调度,使消息可以满足其实时性要求。该调度算法从控制系统稳定性能角度出发,利用控制环的最大允许环延时确定控制环的采样周期,同时基于时间窗口得出控制环中各个节点的起始传输时刻,最终确定了系统静态调度表的结构。最后分析了该调度算法在CAN总线应用中需解决的问题以及未来的研究工作。     

A model-free control structure for the on-line tuning of the semi-active suspension of a passenger car

Comfort and road handling of a passenger car can be improved by replacing its passive suspension by a controlled semi-active suspension. The selection of an appropriate control structure is crucial, since it determines the complexity of the control design and parameter tuning process.This paper presents a flexible and transparent model-free control structure based on (1) physical insights in the car and semi-active suspension dynamics used to linearise and decouple the system, and (2) decentralised linear feedback. The resulting controller can be tuned on-line intuitively using a limited number of physically interpretable parameters.The simplicity of the control structure and the absence of any model of either the car or the shock absorber yields that the code of the controller can run on a low-cost DSP with a minimum amount of memory. The evaluation of experienced test-pilots states that the car with tuned controller behaves naturally, yields comfortable ride on a wide variety of calibrated evaluation tracks and yet is well controlled during all handling manoeuvres.

Web-Based Fault Diagnostic and Learning System

Web-based technology holds great potential for enabling the rapid dissemination of information and facilitating distributed decision-making. This paper presents a novel knowledge-based multi-agent system for remote fault diagnosis, which is composed of diagnostic and learning agents (DLAs), machine agents (MAs) and a central management agent (CMA). Machines are remotely diagnosed by the DLAs through the communication channels between the MAs and the DLAs. In addition, the DLAs can learn new expertise from the users, and the CMA can update the central knowledge base (CKB) shared by all the DLAs with the valuable expertise. When faults that cannot be solved with the present knowledge base occur, the DLA can acquire new knowledge, translate it into rules using a rule builder, and update the rules into the CKB. The CKB will become mature through a continuous learning process. A prototype system has been developed and used for remote fault diagnostics of tool wear in computer numerically controlled (CNC) machining. This revised version with a corrected online cover date was published online in April 2004.
