Conventional and Intelligent Control Schemes for Handling A Helicopter's Pitch Axis

In this paper, a comparative study of conventional LQR controller, optimized PID controller and intelligent Fuzzy logic controller is demonstrated while achieving the desired pitch axis trajectories of a 2-DOF helicopter system. During this process, TLBO optimized PID controller is used to track down the trajectory angle of pitch axis of helicopter system and this performance is compared with inference rules of fuzzy system and a conventional LQR controller. The membership function parameters, exploration - exploitation scheme of optimization algorithm are discussed while addressing the problem of trajectory tracking. The parameter tuning and stable response of pitch axis of helicopter model is achieved on MATLAB/Simulink platform, on which the comparison is accomplished through time response analysis.
