چکیده
|
A recursive gradient identification algorithm based on the bundle method for sandwich systems with backlash-like hysteresis is presented in this paper. in this method,a dynamic parameter estimation scheme based on a subgradient is developed to handle the nonsmooth problem caused by the backlash embedded in the system. the search direction of the algorithm is estimated based on the so-called bundle method. then,the convergence of the algorithm is discussed. after that,simulation results on a nonsmooth sandwich system are presented to validate the proposed estimation algorithm. finally,the application of the proposed method to an x-y moving positioning stage is illustrated. copyright © 2012 ruili dong et al.
