Abstract In this paper, an improved high-order model-free adaptive iterative control (IHOMFAILC) method for a class of
nonlinear discrete-time systems is proposed based on the compact format dynamic linearization method. This
method adds the differential of tracking error in the criteria function to compensate for the effect of the random
disturbance. Meanwhile, a high-order estimation algorithm is used to estimate the value of pseudo partial derivative
(PPD), that is, the current value of PPD is updated by that of previous iterations. Thus the rapid convergence of the
maximum tracking error is not limited by the initial value of PPD. The convergence… More >
