ILC algorithm with fuzzy factor based on vector plots analysis

The common PID type ILC algorithm has invariant convergence rate since its gain matrix is constant. Based on the vector plots analysis and corresponding ILC algorithm, the fuzzy control law is introduced in ILC and a kind of fuzzy factors ILC algorithm is proposed. The new algorithm can regulate the algorithm by adjusting the fuzzy factors according to system error information. Simulations illustrate the effectiveness and superiority of the new algorithms.
