受扰MIMO系统的前馈-PID最优扰动抑制控制

摘要

通过对基于时域状态空间描述的MIMO系统最优扰动抑制控制算法和基于输出反馈的频域PID控制算法的对比分析,设计出系统的最优PID动态补偿网络,实现最优扰动抑制控制.仿真结果表明,该方法对于外部持续扰动具有较强的鲁棒性.%By contrastive analysis of optimal disturbance rejection control algorithm of MIMO systems based on time-domain state-space representatin and of the PID-control algorithm based on frequency-domain output feedback, the system's optimal PID dynamic compensating network was designed to achieve optimal disturbances rejection. Simulation results show that this method has strong robust against external persistent disturbances.
