LQGi/LTR controller with integrators and feedforward controller applied to a Twin Rotor MIMO System

摘要

This paper presents a comparison between LQGi and LQGi/LTR control of a Twin Rotor MIMO System (TRMS)(made by feedback instrument company). The Linear Quadratic Gaussian (LQG) means a linear quadratic regulator with KALMAN filter. LQG/LTR is an LQG controller with Loop Transfer Recovery. For both we introduced an integrator to deal with steady state errors and disturbances. A feed forward controller has been added to improve the tracking performances of the system. The results are in simulation and in real time.
