Abstract

Precision control is essential in most engineering applications, which affecting the outcome of the product. In order to achieve precise motion during the positioning tracking, controller playing vital roles that lead to a better outcome. In this paper, three different control strategies are proposed. The widely-known Proportional-Integral-Derivative (PID) is first designed. Then, the improved PID controller, which is so called Fractional Order (FO-PID) is designed. Followed by the designs of the robust Sliding Mode Control (SMC). The main objective of this paper is to evaluated and compared the performance of these controllers, implemented for positioning or trajectory tracking. The results show that SMC capable to generates most precise trajectory tracking compared with others.
