摘要
针对PID控制器的鲁棒性问题,提出了参数摄动范围下的鲁棒内模PID控制器的优化设计方法,应用极小极大原理设计出基于模型失配的最坏情况下的鲁棒内模PID控制器.通过鲁棒性能指标和控制参数的合理设计,使内模PID控制器较好地适应一定范围的模型不确定性.仿真结果表明,与PID控制器相比,内模PID控制器有很好的鲁棒性.
To solve the problem of PID controller＇s robustness, this paper not only provides the optimizing design method for robust internal model PID controller under changeable parameter, but also designs the controller using the rain-max theory in the worst situation of model mismatch. By the reasonable design of performance index and controller parameter, the robust internal model PID controller can adapt to some model uncertainty. It is proved by simulation that the controller has better robustness than PID controller.
