Abstract :

This research applied both the traditional, Ziegler-Nichols-based and Ziegler-Nichols-based fuzzy control methods to the design of mobile satellite antenna tracking system. Firstly, the antenna tracking and the stabilization loops were roughly designed according to the traditional bandwidth and phase margin requirements. However, the tracking performances would be degraded if the tracking loop gain is reduced due to parameter variations. On the other hand, both Ziegler-Nichols-based PID-type and Ziegler- Nichols-based fuzzy controllers were also applied in the tracking loop to improve the performance. But, only the performances obtained by the fuzzy controllers were better for both the antenna tracking loop with low and high gains, and to reduce the effect of tracking loop gain parameter variations. In addition, the backlash hysteresis effect of gimbals are also taken into consideration for both cases; one can see that the systems obtained by using Ziegler-Nichols-based P, PI, PD and PID type fuzzy controllers are more robust to parameter variations even with the hysteresis effect.
