Abstract

This paper focused on the application of electro hydraulic actuator in positioning of aircraft control surface. The dynamic of the considered system is highly nonlinear due to nonlinear pressure-flow relationship, orifice dynamics, and friction effect. Such nonlinearities offer variation of system parameters. So in order to account for such variations, a linear parameter varying (LPV) model of the system is developed first and fixed structure H controller is designed that can operate within predefine parameter range. The proposed controller is simple structured and has low order compared to conventional ∞ controllers. To test the controller according to real flight condition, an external disturbance (due to air load acting on control surface) is applied. Simulation results on nonlinear system validate the dominant performance of proposed controller as compared to classical PID. Moreover, the proposed scheme found robust under the variation of system parameter.
