High Precision Control of Servo Control System Using The Adaptive Fuzzy Controller |
| Abstract |
This paper proposes the adaptive fuzzy control system using the microprocessor for high precision control of automation systems which exist non-linearities such as saturation, relays, hysteresis, and dead zones. The proposed system, which provides the improvement in terms of the control region in transient and adaptive control, first used the frequency-locked method driving a system to generate a output voltage proportional to the frequency difference of reference input signal and feedback signal for fast transient response, and when the error reaches the preset value, used the adaptive fuzzy control method using fuzzy logic for precision control. The theoretical and experimental studies have been carried out. The presented results from the above investigation show considerably improved performance in the precision control of servo control systems. |
