Modeling and control for variablepump controlling variablemotor
摘要
Abstract
The variablepump controlling variablemotor （VPCVM） is an essential nonlinear system with dualinput, singleoutput and coupling, for which regular control algorithms are ineffective to achieve the required control performances. Based on linearization theory for VPCVM, we propose an improved BangBang control algorithm for tackling the nonlinearity and the unsolvable coupling. First we develop a mathematical model of VPCVM involving the multiplication nonlinearity with the output variable; and then, we linearize the model by using the feedback linearization theory. Based on the linearized model, we develop the improved BangBang control algorithm to achieve the rapid control for VPCVM. Simulation results demonstrate that the proposed algorithm realizes the desired rapid control on VPCVM with performances higher than that of conventional control methods. Furthermore, this algorithm exhibits a strong robustness against the variations of rotational speed and load.关键词
