摘要
基于一种H_∞控制简化算法和鲁棒补偿原理.用串联低通滤波器来解决控制器的物理可实现问题,提出了一种改进的H_∞控制算法。该控制算法求解过程简单,物理意义明晰。仿真和试验结果表明,用此算法设计的H_∞控制器能保证系统闭环性能,且具有较强的鲁棒性。
Based on one simplified H_∞ control algo-rithm and robust compensation theory, this paper pre-sents an improved H_∞ control algorithm, which uses low-pass filter to design a realizable controller. Calculationsof the controller are simple and its physical meanings areclear. Simulation and experimental results show that us-ing the control algorithm. performance of closed--loopsystem is very good and excellent robustness is obtainedtoo.
