Variable pump control variable motor speed regulation system process is equivalent to a quantitative variable pump motor control or dosing pump control variable motor, there is a system overflow losses big, slow and did not play a regulating system potential shortcomings. To overcome these shortcomings, the variable displacement pump detection proposed variable structure control algorithm feedback linearization theory of variable displacement pump variable motor system based on the establishment of the variable displacement pump variable motor control system model, variable pump repair, and for multiplying the nonlinear systems, domestic variable pump, using precise feedback linearization The linear theory of variable displacement pump - variable motor speed regulation system process is equivalent to a quantitative variable pump motor control or dosing pump control variable motor, there is a system overflow big loss this way, adjust the system slow and did not play the potential of other shortcomings. To overcome these shortcomings, the variable pump is proposed variable pump - variable motor adaptive control algorithm. Variable speed pump motor for active closed-loop control, and realize variable displacement pump and variable motor while adjusting the variable motor for servo control based on variable displacement pump. Single neuron adaptive PID control algorithm variable pump control, predictive adaptive control algorithms variable motor control. Given the variable pump - variable motor adaptive control algorithm basic principles and block diagrams, simulation and experimental results show that the algorithm can improve system response speed and reduce the overflow losses.
