本文研究对象输入中未知死区的补偿问题。提出了一种基于等效输入扰动估计的补偿方法。与其他方法不同，该方法不需要死区的确切信息。首先，我们将死区视为一个依赖于输入的扰动，并利用EID估计器对它进行估计，然后将估计值加入到控制输入中，几乎完全补偿死区的影响。仿真结果验证了该方法的有效性。
This paper considers the problem of the compensation of an unknown dead zone in the input of a plant. A new compensation method is presented based on the estimation of an equivalent input disturbance (EID). Unlike other methods, this method does not require the exact information of a dead zone. First, we consider the dead zone as an input-dependent disturbance and employ an EID estimator to estimate it. Then, we incorporate the estimate in the control input and compensate the effect of the dead zone almost completely. Simulation results demonstrate the validity of the method.
