Abstract
The objective of this research is to implement a novel parallel control of the force and the energy-saving in the hydraulic valve-controlled cylinder systems(HVCCS) for simultaneously achieving accurate force control response and high energy efficiency. In order to verify the feasibility of the integrated control system and compare the energy-saving effects, the force control(FC) of the HVCCS can be integrated with two different energy-saving control(ESC) systems, as well as integrating it with a conventional hydraulic system without energy-saving control.
In this study, two different kinds of control algorithm are proposed to realize the integrated control of HVCCS. First, a decoupling self-organizing fuzzy sliding-mode control (DSOFSMC) strategy, which can reduce the fuzzy rule numbers and counteract the coupling effects, is developed for the integrated control of HVCCS. Then an H∞ control algorithm, which can perform good disturbance rejection, is implemented to the concurrent control in the HVCCS.
The experimental results show the outstanding performance of the parallel control in the controlled system with the two proposed controllers. In comparison with conventional valve-controlled systems, the integrated control system with the proposed algorithms can also achieve better force control responses and significant energy-saving effect at the same time.
