Abstract

This paper is concerned with the problem of robust control for electro-hydraulic servo systems driven by double-rod actuators. Firstly, by introducing a linear varying parameter, the system is described as a linear parameter varying (LPV) model. Secondly, based on this LPV model, the strict LMIs-based conditions for the system to be robustly stabilizable are deduced. By solving those LMIs, a parameter-dependent controller is established for the closed-loop system to be stable. Finally, the numerical simulations demonstrate the satisfactory performance of the proposed controller.
