This paper deals with fractional-order reset control systems and their stability. The possibilities of use of a new fractional-order proportional-Clegg integrator (FPCI) in reset applications are investigated. The key feature of this controller is to tune its order alpha to achieve an optimized system performance, especially referred to avoid the Zeno solution. The stability of reset control systems is generalized for such fractional-order systems. Fractional- and integer-order reset controllers are designed and compared for the velocity control of a servomotor. Simulated and experimental results are given to show the benefits of using FPCI on the servomotor performance. (C) 2013 Elsevier Ltd. All rights reserved.
