Several methods for the identification of linear multivariable continuous-time systems from the samples of input-output data are discussed. These include three new methods proposed by the authors. The suitability of these methods for estimating the parameters of the system using recursive least-squares algorithm is compared using a simulated example. The results indicate that the best results are obtained using the block pulse function method as proposed by the authors.

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.

We present an algorithm for solving singular value inequalities over a continuum of frequencies. The algorithm is in two parts: a master algorithm which constructs an infinite sequence of finite sets of inequalities and a nondifferentiable optimization subalgorithm which solves these finite sets of inequalities.

This paper shows how the design of feedback controllers for nonlinear systems may be formulated as an optimization problem with infinite dimensional constraints for which known algorithms may be employed. An important aspect is a method for reducing the time interval, required to insure stability, to a finite value.

The design problem of choosing a set of parameters so that inequality constraints are satisfied for a specified variation of parameter values about their nominal value, is considered. Such problems occur when systems must be synthesized from components whose values are only known to a certain tolerance. Simple algorithms exist for such problems when the constraints are convex. This paper presents an algorithm which is valid for the non-convex case, The algorithm utilizes concepts employed by Eaves and Zangwill in their generalized cutting plane algorithms.

This paper collects a number of scattered results on the solution of both finite and infinite systems of inequalities into a unified whole. In particular, it presents two methods which solve finite systems of inequalities in a finite number of iterations and which use outer approximations techniques for infinite systems of inequalities.

A description will be given of a process consisting of two connected vertical stand-pipes. This physical process is rather simple in the details of its construction, but the relationship between the flows into and out of the standpipes and the levels is nonlinear and complicated. A nonlinear mathematical model will be derived to describe the dynamical behaviour of this system. A control structure with nonlinear multi loop feedforward and linear single loop feedback control will be analyzed and discussed. Simulation and implementation with an experimental laboratory set-up are used to illustrate and demonstrate the behaviour of process with the proposed control structure.
