Abstract :
According to the stability of boiler drum water level, with reference to the dynamic characteristics of drum water level, the water level regulation state-space model is established in this paper. Linear-Quadratic Regulator (LQR) is designed to make the boiler drum water level control system closed loop stable based on the theory of Linear Quadratic Optimal Control (LQOC). Select the appropriate weighting matrices Q and R for MATLAB simulation. The results show that the optimal control system of boiler drum water level based on LQR has a good anti-interference ability and it can help improve the system dynamic response and stability.
