This paper introduces a new study for one-axis servomechanism with consideration the parameter variation and system uncertainty. Also, approach high-performance self-tuning nonlinear PID control was developed to track preselected profile high accuracy. Moreover, comparison between proposed technique well-known controllers (PID Nonlinear PID). The optimal parameters were determined based on COVI...

Abstract— In this paper Fuzzy Lyapunov Synthesis is extended to the design of Type-1 Fuzzy Logic Controllers for nonsmooth mechanical systems. The output regulation problem for a servomechanism with nonlinear backlash is proposed as a case of study. The problem at hand is to design a feedback controller so as to obtain the closed-loop system in which all trajectories are bounded and the load of...

In this study, an industrial sliding-mode servo control system is developed for the motion control of a direct-drive-type elevator-door servomechanism. The mechanical structure and dynamic analyses of an elevatordoor mechanism with an indirect field-oriented induction servomotor drive is described initially. Moreover, a newly designed total sliding-mode control (TSMC) system, which is insensiti...
