N2 - Aiming at the nonlinear of the dead zone of electro-hydraulic proportional valve controlled cylinder system, a self-regulating dynamic compensation algorithm is proposed in this paper. Firstly, the mathematical model of the system is established and the causes of the system dead zone are analyzed. Finally, a control algorithm which can self-regulate the amount of compensation from the dead zone is proposed and the experimental verification is finished. Also, the comparison between the experimental results and the traditional static compensation algorithm results is made. Experimental results show that, compared with the static compensation, the step response is greatly improved by using the dynamic compensation algorithm and the interference from the dead zone to system control is reduced. The target that system can be quickly located with high accuracy is achieved.
