3、 The results are shown in Fig. A.7 and the comparison between the controllers amplitudes are considerable.Section B. A new iterative learning control method for stabilizing a class of nonlinear systems B.1. Introduction In the last two decades, iterative learning control has been extensively studied
4、, achieving significant progress in both theory and application.Conventional iterative learning control (ILC) is a relatively new control strategy that updates the control input to improve the system performance by means of system repetition over a finite time interval 35.In this paper, a new type o
5、f ILC method is presented. Different from conventional methods which control a process in finite time repetitively, by fixing the time and moving through a new virtual axis, called the index, this new mentioned method tries to find the best value for the control at this time step. In this process, u

Problem formulationIn this paper, we focus on the design of controllers for a class of SISO nonlinear system whose dynamical equation can be expressed in the following form 69:x(n) = f (X) + g(X)u (5)where X = x, x, . . . , x(n1). It can also be expressed as below;where t i
