This paper presents the development and implementation of a PID-based control system for a series hydraulic hybrid propulsion system. At first, a configuration of the system is discussed and modeled in MATLAB/Simulink environment. Then, based on the established model, a two-level control system is developed. Monitoring demands from driver and current states of the system, the top-level controller sends out appropriate demands for the component-level controllers to meet the driver requests under any condition. Performance of the control system is evaluated in different situation of driver demand. The established model provides an efficient tool for control system development. The robustness of the proposed control system allows developing and evaluating the benefit of different power management strategies for the series hydraulic hybrid propulsion system.
