Control System Design by Dissipative System Theory

本文从理论和仿真两方面研究了时滞系统的镇定问题。在以下几个方面得到了一些理论结果。将时滞系统的镇定问题转化为零时滞系统的相位裕度设计问题。结果表明，相位裕度设计问题等价于一个H ∞控制问题，因此，该问题很容易用传统的控制设计方法来解决，仿真结果已在executed.to上给出。飞机的控制系统设计已经沿着MIL规范进行了模拟。对柔性结构的控制系统进行了实验仿真，从理论上提出了一种时滞系统的控制设计方法，并对具有时滞的物理系统进行了实验仿真。

This research has investigated a stabilization problem for time-delay systems, in theory and simulation. Some theoretical results have been obtained in the following.- The stabilization problem with time-delay is reduced into a phase margin specification problem for zero time delay systems.- It is shown that the phase margin specification problem is equivalent to an H-infinity control problem ; cons equently, the problem is easy to solve by conventional control design methods.Simulations have been executed.to illustrate the theory as below.- Control system design of airplane has been simulated along the MIL Specification.- Experimental simulations for control system of flexible structures have been executed.In summary, this research has theoretically developed a control design method for time-delay systems and the results have been verified by experimental simulations, for physical systems with time-delay.
