SLIDING MODE CONTROL AND ESTIMATION FOR MECHATRONIC ACTUATORS

Abstract

This paper deals with challenges associated with the Mechatronic actuator control within automotive systems where in many cases sensors are not available or are costly for application. Following recent advances in microprocessors technology where high speed is achieved and is still rising in spite of declining price, this paper investigates possibility of heaving dedicated microprocessors for actuator control. With this consideration implementation of SMC has been investigated for estimation and control where in some cases these options have been considered as a fall safe mode of operation. Electric Waste Gate is taken as an example for this investigation. Combination of SMC and Sensitivity Based Adaptive Controls (SBAC) has been investigated with the use of simulation results.

Keywords: parameter estimation, system identification, adaptive control
