摘要
针对一阶时滞过程设计了一种分数阶内模PID控制器。根据分数阶理论和内模控制原理,提出了一种分数阶内模PID的定义形式,研究了滤波参数与闭环系统性能的关系,得出了分数阶内模PID控制器。仿真结果表明,该方法有效地提升了系统的控制品质。
A frctional oder internal model PID controller is designed for first-order lag plus delay. According to the theory of fractional calculus and internal model PID controller are combined, a fractional internal model PID definition is presented, and the relationship between the filter parameter and the performance of the closed-loop system is studied, and the fractional internal model PID controller is obtained. The simulation results show that this method can effectively improve the control quality of the system.
