Aiming at the uncertain linear system, a robust guaranteed stability control system analysis and design method with crossover term in performance index is proposed. An improved robust hysteresis equation is established and the sufficient conditions for robust guaranteed stability of the closed-loop system are given. , The description form of gain and phase margin, and the design method of robust guaranteed stability controller, and the design and simulation of the robust guaranteed stability control system are given by taking the papermaking process as an example.
