摘要 通过恰当地选择输出信号,将不确定干扰入常微分方程系统,从而可以利用高增益观测器来估计不确定干扰,这样未知干扰可以由其估计值抵消掉.理论证明,该方案是行之有效的. The unknown disturbance was introduced into the ordinary differential equation system by proper choice of the output signal.Therefore,this disturbance can be estimated effectively by high-gain observer and canceled by its estimation.It is proved that the strategy is effective.
