A new dynamical model is developed to overcome the limitations of the existing results. In this model, two independent failure processes with Markovian transition probabilities are considered: one for plant components and the other for control actuators. Moreover, the proposed model takes into consideration failures in control actuators with internal dynamics. It is shown that the exponential stability in the mean square is sufficient for the almost sure asymptotic stability, and a necessary and sufficient condition for the exponential stability in the mean square for linear FTCS is derived. Some previously known results are shown to be special cases of these new results. A numerical example is included to demonstrate the theoretical analysis.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

For suitable notions of complexity and accuracy, we characterize the class of plants of bounded complexity which, after interconnection with a given controller, achieve a guaranteed accuracy of the controlled system behavior. It is shown that the controlled systems that can be obtained in this way are parametrized in terms of the most powerful unfalsified model of reduced controlled system data. The key consequence of this result is that it translates the approximate controlled system identification problem to a realization problem.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

Adaptive tracking control of nonholonomic mobile robots by computed torque 基于计算力矩的非完整移动机器人自适应跟踪控制

A velocity controller is first designed for the kinematic steering system to make the tracking error approach zero asymptotically. Then, a computed torque controller is designed such that the true mobile robot velocity converges to the desired velocity controller. In each step, the controllers are designed independently, and this will simplify the controller design. Moreover, the regulation problem and the tracking problem will be treated using the proposed controller. In particular, the mobile robots can globally follow any path such as a straight line, a circle and the path approaching the origin. Furthermore, the problems of back-into-garage parking and the parallel parking problem can also be solved using the proposed controller. Some interesting simulation results are given to illustrate the effectiveness of the proposed tracking control law.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

Statistical QoS guarantees, which provide a minimum rate but allow for infrequent violations of service, have the potential for greatly improving the quality of these applications by mitigating the effect of network congestion. We investigate a measurement-based admission control and monitoring algorithm that provides a minimum guaranteed rate and maximum scheduling latency, called a rate-latency bound, to traffic classes with the proviso that the guarantee may be violated for a small fraction of time. The algorithm estimates the demand for resources online by measuring the actual rate of each traffic class for particular choices of scheduling latency, and estimates the QoS violation rate using model fitting and extrapolation. The generality of these measurements allows one to provide a single admission control algorithm that can be used with many proposed guaranteed-rate servers.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

Keane, J. Yu, F. H. Bennett, W. Mydlowec, O.

The method described in this paper automatically makes decisions concerning the total number of processing blocks to be employed in the controller, the type of each block, the topological interconnections between the blocks, the values of all parameters for the blocks, and the existence, if any, of internal feedback between the blocks of the overall controller. This design process can readily combine optimization of performance (e.g., by a metric such as the integral of the time-weighted error) with time-domain constraints and frequency-domain constraints. Genetic programming is applied to two illustrative problems of controller synthesis: the design of a robust controller for a nonminimal-phase plant and the design of a robust controller for a three-lag plant. The PID compensator of Astrom and Hagglund (1995) for the three-lag plant delivers credible performance. The automatically created controller is better than 7.2 times as effective as the previous controller as measured by the integral of the time-weighted absolute error, has only 50% of the rise time in response to the reference input, has only 35% of the settling time, and is 92.7 dB better in terms of suppressing the effects of disturbance at the plant input.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.
