摘要
针对无刷直流电流电机双闭环调速系统转速调节器存在的非线性饱和特性,提出一种IMC-PID抗饱和控制方案。首先根据内模控制原理设计出转速环和电流环的IMC-PID控制器,然后引入可行性参考输入的概念,设计出基于条件技术的转速环IMC-PID抗饱和控制器,最后为验证IMC-PID抗饱和控制器的可行性,将该控制器应用于无刷直流电机双闭环调速系统中。仿真结果表明:该控制器不仅具有的良好的抗干扰性和鲁棒性,而且改善了系统的动态性能,有效抑制了饱和现象的影响。
An IMC-PID anti-windup control scheme was proposed to solve the saturation nonlinearity of the speed regulator in the double closed-loop speed control system of the brushless DC motor.Firstly,IMC-PID controller of speed loop and current loop was designed according to the principle of internal mode control.Secondly,the concept of feasibility reference input was introduced to design the speed loop IMC-PID anti-windup controller based on conditioning technique.Finally,in order to verify the feasibility of IMC-PID anti-windup controller,the controller was applied to the brushless DC motor double closed-loop speed regulation system.The simulation results show that the controller not only had good anti-interference and robustness,but also improved the dynamic performance of the system and effectively suppresses the influence of saturation.
