CHAOTIC TRAJECTORY TRACKING FOR AN ELECTRO-HYDRAULIC ACTUATOR

Various robust control techniques such as Integral Block Control, Sliding Mode Control and H-infinity Control are combined to design a controller, forcing an electro-hydraulic actuator driven by a servovalve to track a chaotic reference trajectory. This approach enables to compensate the inherent nonlinearities of the actuator and reject external disturbances. The capabilities of the approach are illustrated in a simulation study.
