Abstract

In this paper, aiming at the phenomenon that the dead zone and hysteresis of three-way proportional pressure reducing valve (TPPRV) will seriously affect the control accuracy of construction machinery, a polynomial excitation current compensation controller (PECC) is designed, which is novel and easy to realize in engineering. Firstly, the mathematical model of TPPRV is established, and the dead zone and hysteresis of TPPRV are quantitatively analyzed by using the performance test platform of proportional pressure reducing valve. Secondly, the design principle of PECC is expounded, and the controller model is deduced theoretically. The proposed PECC has two main advantages. One is that the method does not need to establish the nonlinear model of dead zone and hysteresis, and the other is that the method can compensate the dead zone and hysteresis simultaneously. Finally, the compensation control performance of PECC is verified by using the performance test platform of proportional pressure reducing valve. The experimental results show that PECC can greatly reduce the adverse effects of dead zone and hysteresis on TPPRV, and has great applicability under different working conditions. Relevant research results can significantly improve the proportional control accuracy of TPPRV, which has a certain engineering value.

Keywords Dead zone compensation, hysteresis compensation, polynomial excitation current compensation controller (PECC), three-way proportional pressure reducing valve (TPPRV).
