Stability Analysis of TRMS Using Optimal Control Technique

Twin rotor (multi-input multi-output) MIMO plant is highly nonlinear with cross coupling mechanism is a test rig of physical helicopter. The main goal of this work is to be stabilizing this system configuration for the stability analysis and for this mathematical modelling of TRMS is done first. Optimal controller is applied to TRMS based on state feedback technique. Simulation results in frequency domain illustrate that how the system response changes, and system become stable with optimal controller.
