Analysis of autopilot system, integrated with modelling and comparison of different controllers with the system. (English) Zbl 1485.93397

Summary: In this paper, we study an airplane for incorporating autopilot setting in it. The basic approach includes controlling the pitch angle by controlling the angle of deflections that occur at the elevator of an airplane. For the, different controlling techniques have been used. These include, integrating the system with a PID controller, fuzzy controller, fuzzy plus PID controller and a robust controller. It is observed that steady-state error is quite significant in the system without any control mechanism; therefore, different automatic controlling methods have been integrated with the system. The results of simulated systems reduce the steady-state error with the use of different controllers. We observe the results of the different controllers to compare the overshoot and rise-time parameters. Therefore, we can achieve an autopilot system with optimum efficiency and robust mechanism.
