Pressure control of fixed displacement variable speed radial piston pump using PID controller

In the present studies attentive to control the variable pressure of fixed displacement variable speed radial piston pump by controlling the angular speed of pump-motor system with a PID controller at ramp and wavy type load. The pressure-flow simulation of pump designed in MATLAB Simulink with an appropriate silencing groove valve plate of the pump. The proposed PID controller designed in Simulink framework to control the pump-motor speed to accomplished the demand pressures at ramp and wavy type load and the load accustomed by varying the needle valve orifice area. PID controller gain value optimised by minimising the tracking error of the pump pressure responses.Copyright (c) 2021 Elsevier Ltd. All rights reserved.
