Effect of Different Controllers on Performance of Dish Antenna Positioning System for Distributed Mobile Telemedicine Nodes
Abstract
The effect of different controllers on performance of dish antenna positioning system for distributed mobile telemedicine nodes has been examined. The dynamic equations of a dish antenna position control system used in distributed mobile telemedicine nodes were obtained in the form of a transfer function models in continuous time domain. The transfer function models were transformed into equivalent state space models. The state space equations were represented by different features of Simulink used to model the system in MATLAB/Simulink environment. The performance of the system was studied in terms of stability, controllability, and observability. A state feedback controller was designed and implemented in MATLAB/Simulink. Simulations were conducted for the designed full state feedback controller and existing schemes namely, proportional integral and Derivative (PID) controller and PID plus pre-filter method. The results revealed that the proposed system provided the best overall performance criteria compared to existing systems with rise time of 0.45 s, settling time of 1.22 s, peak time of 0.945 s, and peak percentage overshoot of 4.91%.
