Abstract: In this paper, fuzzy self-tuning controller is introduced first. The fuzzy model is built according to the experience of PID parameter tuning with fuzzy set theory. Parameter tuning is achieved by use of fuzzy ratiocination and decision according to actual response, which is applied for control towards robot. Mathematical model of two-link robot has been built as well as its geometric and dynamical equations through coordinate transformation and matrix operation. Finally, fuzzy PD controller with self-tuning method is applied to realize control towards robots. Simulation in Matlab has been carried out whose result shows that the control method proposed in this paper has better performance than the traditional ones.

Abstract: The paper presents the making of driver-motor-reducer and turntable system, and builds a mathematical model of this system. The design of a self-tuning PID controller and the simulation of the whole system are realized by using the MATLAB fuzzy logic tool. The simulation results show that the turntable servo system with the fuzzy self-tuning PID controller has a slight overshoot, fast response, good accuracy and robustness etc.
