| Abstract | ||
| This paper proposes a controller design of a nonlinear model of an internal combustion engine based on linear quadratic regulator (LQR) technique. The design takes into consideration the effect of external disturbances that occurs during the operation of system. The equations of motion are linearized according to the perturbation theory in order to inspect the dynamic stability of the engine motion, and the subsequent design of appropriate feedback controllers for the system, which can be obtained by solving the LQR problem. The results show that the proposed controller has good performance and stability than PID controller. The simulations have been carried out in Matlab/Simulink environment. | ||
