摘要
以Boost变换器的控制策略为研究对象,将自抗扰控制技术应用到Boost变换器的控制策略中,使被控系统不但具有良好的动态特性,而且对参数变化具有较强的鲁棒性。同时针对自抗扰控制参数难以整定的特点,介绍了自抗扰控制的参数整定基本原则,对Boost变换器进行自抗扰控制仿真,并和PID控制进行对比。最后,用时间尺度概念对Boost变换器的自抗扰控制进行参数整定。仿真结果验证了该方法确实可行。
Taking the control strategy of Boost converter as the study object,the active disturbance rejection control is applied to the control strategy of Boost converter.The controlled system not only has good dynamic characteristics,but also has strong robustness to the variations of system parameters.The basic principle of parameter tuning for active disturbance rejection control is introduced,and the simulation of active disturbance rejection control of Boost converter is carried out and compared with PID control.At the same time,the parameters of disturbance rejection controller are tuned by the concept of time scale,which solves the problem of the parameter setting.Finally,the simulation results of the Boost converter verify that the method is feasible.
