Control Law Design for Twin Rotor MIMO System with Nonlinear Control Strategy

Abstract: Modeling of complex air vehicles is a challenging task due to high nonlinear behavior and significant coupling effect between rotors. Twin rotor multi-input multioutput system (TRMS) is a laboratory setup designed for control experiments, which resembles a helicopter with unstable, nonlinear, and coupled dynamics. This paper focuses on the design and analysis of sliding mode control (SMC) and backstepping controller for pitch and yaw angle control of main and tail rotor of the TRMS under parametric uncertainty… Show more

“…However, applying Lyapunov functions does not always give good performance and accuracy, and the use of non-linear controllers may lead to adverse effects such as chattering, oscillations, and noises. Ilyas et al [57] designed first-order SMC and BC schemes to deal with the oscillations and chattering in pitch and yaw angles where BC shows better results in handling them compared to SMC. Concerning the strong cross-coupling effect and non-linearity between the main and tail rotors, Raghavan and Thomas [58] presented a model predictive control (MPC) design, via systematical and experimental means.…”

“…In a few decades ago, many researchers proposed the different types of control techniques to control the performance of TRMS on horizontal and vertical planes. For instance, the proposed control techniques that applied in TRMS system such as Proportional-Integral-Derivative (PID) controller [4][5][6][7][8][9], Linear Quadratic Regulator (LQR) [10], Sigmoid-PID (SPID) controller [11], Fractional-order PID (FOPID) controller [12][13][14][15][16][17], Fuzzy Logic controller [18], Sliding Mode Controller (SMC) [19][20][21], Fuzzy-PID (FPID) controller [22][23][24][25][26] and Model Predictive Controller (MPC) [27]. Nevertheless, researchers and scientific community put the greatest attention in the combinations of different type control technique based PID controller.…”
