BILINEAR MODELLING AND STATE-FEEDBACK CONTROL OF AN ELECTRO-HYDRAULIC DRIVE

Abstract A continuous-time bilinear model is identified for an Electro-Hydraulic Servo Drive. Based on this identified model a state-feedback controller is designed. The controller consists of a feedback linearizing control law and a tracking control algorithm. The unmeasurable state variables are determined with a bilinear observer from the position measurements of the drive. A new method is introduced to design observers for bilinear systems.
