摘　　要：通过对执行机构实验数据的分析推导出其数学模型;针对机构存在死区的特点设计了逆变换补偿的控制算法,消除了死区对控制系统的不良影响。使用MATLAB从理论上检验了改进算法控制的有效性,获得了相应控制参数。实车验证结果表明:该方法可以有效的消除由死区导致的控制误差。Through the analysis of experimental data,the actuator mathematical model was deduced. According to the characteristics that the actuator had the dead-zone,the control algorithm regarding the dead-zone inverse transforming compensation was designed to eliminate the adverse impact of dead-zone for control system. The effectiveness of improved algorithm was validated theoretically by MATLAB,and the corresponding control parameters were obtained. Real vehicle experiment results show that the proposed method can effectively eliminate the control deviations caused by dead-zone.
