Summary This paper is concerned with transient performance in tracking problem for switched linear systems with input saturation. A design procedure for constructing the composite nonlinear feedback (CNF) control law is developed. Under the average dwell time scheme, the controlled output of the closed‐loop switched system tracks asymptotically a step reference by CNF control technique without exceeding the saturation limit. At the same time, the desired transient performance with quick response and small overshoot can be achieved. In addition, the proposed method is applied to the control of turntable servo system. The example of turntable demonstrates the feasibility and effectiveness of the results proposed. Copyright © 2015 John Wiley & Sons, Ltd.
