A Genetic Approach for Auto-Tuning of Adaptive Fuzzy PID Control of a Telescope's Tracking System.

This paper devotes to design of Fuzzy Adaptive PID position Controller of servo drive of telescope's axis to tracking space objects with high accuracy. Suggested method automatically adjusts membership functions and control rules of fuzzy controller using an evolutionary algorithm. Finally, simulation and experimental results demonstrate that presented controller is effective in high-precision control due to elimination of stepping mode that may be occur in multi-mass system with nonlinear friction torque at very low tracking speed for space objects.
