Design and Evaluation of the PID, SMC and MPC Controllers by State Estimation by Kalman Filter in the TRMS System

Abstract:

The Twin Rotor Mimo System (TRMS) consists of two rotors namely tail rotor (∅) and main rotor (ψ). The main objective of this article is improving the stability of the TRMS system in rotation and elevation. To achieve that, a pbkp_redictive controller based on the model (MPC), and a sliding mode controller (SMC) were implemented. The analytical modelling is based on the study of the system dynamics to obtain a linear model. Additionally, concepts of control involved in the design of the MPC, PID and SMC controllers are considered. The controllers were evaluated on simulation and on the real TRMS system by performing several tests. In these tests the metrics considered were the response of the system and the control signal. The results show a comparison of settling times, rise times, integral of the absolute error (IAE) and integral of the squared error (ISE). We found that SMC controller have the best performance in comparison with PID and MPC controllers.
