Iterative Compensation Method Applied in the Simulation Research of the Trolley Collision

采用频域迭代的方法逐步修正驱动信号,实现对输出信号在幅值和相位上的补偿,使系统的输出逼近期望响应信号。驱动信号迭代算法是迭代补偿算法的核心内容,为了消除非线性的影响,给出了详细的驱动信号频域迭代算法,并运用到模型中,验证了此算法的可行性和有效性。

The frequency domain iteration was used to revise the driving signal gradually, the amplitude and phase compensation of the output signal was achieved, thus it enabled the output of the system to approach the desired response signal. The iterative algorithm of the driving signal is the core of iterative compensation algorithm, in order to eliminate the non-linear influence, the detailed driving signal iterative algorithm in the frequency domain was given and it was utilized in the model, at last it validated the feasibility and the validity of this algorithm to the collision system.
