Self-Tuning Fuzzy Controller

Design of Self-Tuning Fuzzy Logic Controller

During the past several years fuzzy control has emerged as one of the most active and fruitful areas of research in the field of control engineering especially, in the realm of industrial processes. Fuzzy control, based on fuzzy logic is a logical system which incorporates human thinking rather than traditional analytical methods. Therefore, this paper aims to explore the utility of this contro...

Self-Tuning Fuzzy PI Controller (STFPIC)

A Self-tuning Fuzzy Robotic Force Controller

Most industrial robots are controlled as position servo-based manipulators. This has made most advanced force control algorithms unpractical and difficult to implement. In this paper a position based fuzzy PID force controller is proposed to regulate contact force of a six degree of freedom industrial robot where the environment contact stiffness varies considerably. Based on a relationship bet...

A PI-type fuzzy controller with self-tuning scaling factors

In this paper, a self-tuning fuzzy controller with a smart and easy structure is presented. The tuning schemes allow us to tune the scaling factors by only seven rules. The aim of a controller is to obtain a satisfactory performance, such as the rise time, the overshoot, the steady-state error for the step response. Simulation results of a third order system with time-delay show a better perfor...

Self-tuning Fuzzy Speed Controller of Travelling Wave Ultrasonic Motor

Aiming at the nonlinear characteristic of ultrasonic motor, some control strategies have been proposed to control the rotating speed of ultrasonic motor. But most of these strategies are too complex to realize using a low-cost embedded device. In this paper, a simple fuzzy speed controller is designed for ultrasonic motor. Until now, there has no mature and theoretic design method of fuzzy cont...
