In this paper the behaviour of 2-D discrete systems which contain a finite number of memoryless nonlinearitics is considered. Sufficient conditions for the nonexistence of limit cycles are derived using a frequency domain approach analogous to that used in [1]. The conditions derived are shown to be more general than those already given in [1] and [5]. Also presented are the extensions to the higher dimensional case as well as a simplified check of that condition. An algebraic test, which guaranties the nonoccurence of overflow oscillations in a discrete system in the state space, is formulated based on the results of [7] and on the properties of quasidominant matrices. Finally, the quantization error due to the finite word length of a first order 2-D digital filter is considered and formulae for the amplitude bounds and mean square are given.

This paper presents a new method for calculating a rational transfer function matrix using a Walsh expansion of the impulse response matrix. The algorithm proposed appears to be computationally convenient owing to certain properties of the Walsh functions. An example is given to illustrate the method.

An examination is made of linear regulator problems with an additional cost for applying a nonzero control at each instant. The dual of this problem is the least-squares filtering problem with a cost for taking measurements. Because a solution to the general problem involves solving a two point boundary value problem in nonlinear matrix differential or defference equations, two easily-computed suboptimal control schemes and some useful bounds are proposed. A class of problems is also delineated for which the optimum solution has some special properties which enable it to be computed simply and directly.

This book introduces an optimal iterative learning control (ILC) design framework from the end user's point of view. Its central theme is the understanding of model dynamics, the construction of a procedure for systematic input updating and their contribution to successful algorithm design. The authors discuss the many applications of ILC in industrial systems, applications such as robotics and mechanical testing.
The text covers a number of optimal ILC design methods, including gradient-based and norm-optimal ILC. Their convergence properties are described and detailed design guidelines, including performance-improvement mechanisms, are presented. Readers are given a clear picture of the nature of ILC and the benefits of the optimization-based approach from the conceptual and mathematical foundations of the problem of algorithm construction to the impact of available parameters in making acceleration of algorithmic convergence possible. Three case studies on robotic platforms, an electro-mechanical machine, and robot-assisted stroke rehabilitation are included to demonstrate the application of these methods in the real-world.
With its emphasis on basic concepts, detailed design guidelines and examples of benefits,
Optimal Iterative Learning control
will be of value to practising engineers and academic researchers alike.
