Abstract A method for fuzzy robust tracking control is proposed, which is used for solving aerospace vehicle's (ASV’s) attitude tracking problem during reentry. Based on TS fuzzy model of uncertain reentry attitude dynamics with external disturbance, the tracking errors of reference signals by attitude angle tracking are studied. The constraint of the exponential stability of the tracking error is obtained by introducing fuzzy feedforward. With the premise of stabilization control being the basis of tracking control, a fuzzy feedforward tracking controller and a H_∞ fuzzy stabilization controller with pole constraints are designed. The control problem can be solved by using LMI and FLC tools of Matlab. The simulation results demonstrate the effectivity of the proposed method.
