摘要：A nonlinear mathematical model of the flow-coupled secondary regulation system was established. Then, the exact feedback linearization was applied to transform the system into a linear one by coordinates transformation and state-space feedback based on its nonlinear model. Furthermore, the zero dynamics was analyzed to prove the stability of the system so as to verify the feasibility of the exact linearization control scheme. And the LQR controller was design on the basis of the exact linearization control scheme. Finally, the experimental results show that the Flow-coupled secondary regulation system using the LQR controller based on the exact linearization control scheme has good performance and does better than PID controller when it works far from zero point.
