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 control the complex behaviors occurring at the H-bridge converters, the chaos controlling technology of Washout filter is introduced into the H-bridge converters, which controls the chaos appearing in the H-bridge DC chopper and AC inverter respectively. The chaos control effect, when the system parameters are, or are not disturbed, is also analyzed. In accordance with the discrete model of the system with chaos control, Jacobian matrix is gained, and the restrictions of the control coefficients brought by Washout filter are deduced. The numerical simulation results show that the chaos which exists in the two working modes of H-bridge converter can be controlled effectively by this method, even can exhibit certain robustness and disturbance-rejection ability when the system parameters are perturbed.
