低阶时滞过程的伪预测PI／PID控制

基于单位反馈控制结构,根据期望的闭环传递函数设计得到了一种伪预测PI/PID(ADQPI/ADQPID)控制器。这种控制器只有一个可调参数,可调参数与系统动态响应性能和鲁棒稳定性之间存在直接关系,只需单调的调节控制器参数,便可实现系统的动态响应性能与鲁棒稳定性之间的最佳折衷。仿真实例表明,这种控制器在扰动和模型失配的情况下仍然具有良好的控制性能和鲁棒稳定性,是一种值得在实际工程中推广运用的新型控制器。

Anti-delay Quasi-PI/PID Control of Low-order Time-delay Systems

Based on single loop feedback control structure,a controller named anti-delay quasi-PI/PID(ADQPI/ADQPID)controller is proposed.The controller designed according to desired closed loop transfer function has only one tuning parameter which has clear physical meaning,and both the dynamic performance and robust stability can be satisfied.Simulation results show that ADQPI/ADQPID controller outperforms traditional PID controllers in dynamic performance,disturbance rejection and robust stability,which shows its value in industrial application.
