摘要:
提出一种串级状态反馈控制系统,其纯滞后因子用m阶模型逼近,外回路串入一个积分器,按最优传递函数设计整个系统,内回路引入状态观测器,构成状态反馈子系统,按状态反馈增益阵和状态观测器的协调优化设计子系统,从而实现纯滞后过程的鲁棒二自由度控制.仿真结果表明:所设计的串级状态反馈控制系统同时获得良好的给定值跟踪特性和干扰抑制特性,具有良好的控制性能和鲁棒性.
Abstract:
A kind of cascade system with state feedback was presented. The m-th order model was used to approximate the time delay factor, and then the outerloop of the system was joined with an integrator, the whole system was designed according to the optimal transfer function. The innerloop of the system was joined with the state observer, then state feedback subsystem was constituted. The subsystem was designed in terms of method coordinating work state between the observer and the controller. So the cascade system with state feedback was constituted for the process with time delay. The simulation results show that the designed cascade system with state feedback can trace the set-value and suppress the interference simultaneously, possess some satisfactory control performance and high robustness.
