Optimized LQR Controller Design for Control of MIMO Systems based on Real Coded Genetic Algorithm
Year: 2026
Type: preprint
Abstract: In this work, an optimal linear quadratic regulator (LQR) based controller is designed to control the twin rotor MIMO system (TRMS). To achieve the best possible system performance, the settings of the LQR controller are improved by the use of a real coded genetic algorithm (RCGA). The control of TRMS is a challenging task due to its strong nonlinear characteristics and high cross-coupling effects. This work additionally tests the robustness of the developed controller using the multi-channel output gain and delay margin. This work also tests the developed controller's ability to reject disturbances. The plotted output responses show the efficacy of the designed controller.
