Résumé
A new control type for stick-slip microsystems is proposed in this paper : the voltage/frequency (U/f) proportional control. It gives more precise results relatively to the classical control algorithm. It is also an englobalization of two classical controllers : the sign and the classical proportional controllers. A high stroke model of a stick-slip microsystem is first given. Then, we theoretically analyse the performances of the closed loop process with the U/f controller. Finally, we gives some experimental results obtained different values of the proportional gains.
