For the huge energy losses of the conventional hydraulic valve-controlled servo control system, a new Multi-level Pressure Switching Control System (MPSCS) was coined and proposed in this study to address this issue. First, the discrete force distribution and switching rules of MPSCS was designed for conducting the four-quadrant working principle. Second, the hybrid control strategy was designed and applied for a displacement control system with three-level pressure rails. Finally, an experiment rig was established to validate proposals above in this study. The experimental results approved the pump input power and throttling losses of MPSCS was decreased dramatically compared with the conventional displacement control system, but the response time, position jitter etc. were still challenges to MPSCS.
