Position Control for Laws for Electromechanical Actuator

Various methods in order to control an electromechanical actuator position are presented here. For the device undergoing significant variation of load, we focalise more particularly on the robust character of these control laws. This paper proposes comparative performance for a particular profile including different motions range and variation of loads. The solutions suggested (RST regulator, state space feedback and series regulators) are tested on an experimental model. The device with teaching vocation is made up by one plate making it possible to move loads in a rectilinear way by the means screw and nut put in rotation by a motor supplied with a static converter of 4 quadrants structure
