摘要: 采用增量谐波平衡(IHB)方法导出一类分段线性电路系统稳态周期响应的计算格式,并对该系统进行了数值模拟,作出了特定控制参数下系统周期响应相图,同时获得了控制参数在某一带宽内变动时的系统响应特性,其结果与Runge Kutta方法进行了对比.

Abstract: IHB computation scheme of the periodic solutions for a class of piecewise-linear circuit systems is derived and the relevant numerical simulation is carried out. Phase planes under some specific control parameter values, as well as the system response property within a band of control parameter values, are plotted with the results compared with those of the Runge-Kutta method. It is shown that the IHB computation scheme proves to be an effective way of analyzing nonlinear problems in engineering practice.

Key words: incremental harmonic balance, piecewise-linear, periodic response, attractor
