【摘要】 针对热连轧监控AGC大时滞系统的复杂性,基于简化的数学模型,给出了一种新的ADRC设计及实现方案,以满足高精高速轧制要求.在回路中增加了一个单位增益环节,提高了ADRC参数的通用性;并将各子系统改用线性函数,实现更加简单.仿真结果表明,尽管各控制器的最佳参数均采用变尺度混沌优化方法得到,但ADRC的抗扰性和鲁棒性明显优于常规的Smith预估器和PID.更多还原

【Abstract】 According to the complexity of Monitor AGC system with large time delay for hot strip mill,a new Active Disturbance Rejection Controller(ADRC)was proposed to satisfy high accuracy and speed requirement.In order to improve the versatility of ADRC parameters,a unit gain was added in the loop.Based on the simplified model,the presented ADRC consists of linear functions which make it easier to realize.With the mutative scale chaos optimization method,the simulation results show that the optimized ADRC produces better performance,such as disturbances rejection and robustness,than the conventional Smith Predictor and PID controller.更多还原
