Iterative Learning Control for Linear Discrete Systems with Input Disturbances
نویسندگان
چکیده
This paper is concerned with the ILC control problem for LTI discrete systems. The stability robustness plays a much more fundamental role in ILC than in more routine forms of feedback control. Of particular interest in this work, the iterations can eliminate the influence of disturbances. Based on a summation inequality, a sufficient condition to have a H noise attenuation for this system is given in terms of linear matrix inequalities (LMIs). Finally, numerical examples are presented to illustrate the potentialities of the new conditions presented in this paper. KeywordsIterative Learning Control (ILC), repetitive processes, disturbances systems, linear matrix inequalities, stability along the pass, H -norm.

Eigenvalue Assignment Of Discrete-Time Linear Systems With State And Input Time-Delays
Time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. The stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. It is well-known that the stabi...

متن کاملA discrete-time stochastic learning control algorithm
One of the problems associated with iterative learning control algorithms is the selection of a “proper” learning gain matrix for every discrete-time sample and for all successive iterations. This problem becomes more difficult in the presence of random disturbances such as measurement noise, reinitialization errors, and state disturbance. In this paper, the learning gain, for a selected learni...

Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...

This paper presents the design of a robust Iterative Learning Control (ILC) algorithm for linear systems in the presence of parametric uncertainties and repetitive disturbances. The robust ILC design is formulated as a min-max problem with a quadratic performance index subjected to constraints of the control input. Employing Lagrange duality, we can reformulate the robust ILC design as a convex...
