为了对H桥变换器工作过程中出现一系列复杂行为进行有效控制,将Washout滤波器混沌控制技术引入到H桥变换器中,分别对H桥作为直流斩波器和逆变器时出现的混沌现象进行控制,同时分析了系统参数未受扰动和受扰动时的混沌控制效果。根据引入混沌控制后系统的离散迭代模型得到了系统的Jacobian矩阵,并推导了Washout滤波器混沌控制的控制系数的限定条件。数值仿真结果表明,该方法能够对H桥变换器两种工作形式中出现的混沌行为进行有效控制,并且在系统参考受扰动时也能表现出一定的鲁棒性和抗扰性。 In order to effectively control a series of complex behaviors during the operation of the H-bridge converter, the Washout filter chaos control technology is introduced into the H-bridge converter, and the chaos occurs when the H-bridge is used as the DC chopper and the inverter, respectively At the same time, the chaos control effect when the system parameters are unperturbed and disturbed is analyzed. The Jacobian matrix of the system is obtained according to the discrete iterative model of chaotic control system. The definition of the control coefficient of the chaotic control of Washout filter is derived. The numerical simulation results show that this method can effectively control the chaotic behavior in the two working forms of the H-bridge converter and also show some robustness and immunity when the system reference is disturbed.
