β¦ Synopsis
For monovariable systems, if the nominal transfer function is irreducible the minimal order is tlw clqwr of'tllr(/~~tl(~l~litl~ltot.~)ol!'l~ol~liCtl. In multivariable systems. this order is (I/ krst equal to the degree of the last common multiple of the denominators of the transfer matrix function entries. Without taking into account this property. many different methods were developed to reduce the order of multivariablc systems which lead to order models that are in fact of higher ordcl than the initial system (1). Recently, the authors in (2) proposed a method as ;I technique for the ortkt rwhr~tiot~ r~f'litww rllftltircrtiohlc .s~~.srm~.s.

Application of two-time scale discrete singular perturbation methods have been limited to the linear systems. The area of discrete-time non-linear systems has received little attention.

Sumraary--Properties and methods of generation of pseudo-random binary signals are discussed. A theory of linear modelling is developed for multivariable systems in which these signals form the inputs. Modelling with delay operators and exponential weighting function operators is considered.

Certain basic operations, the most important being the determination of the effect oJ feedback on a matrix transfer function, can be performed algebraically rather than numerically at specific frequencies, enhancing the power of existing procedures for designing linear multivariable control systems.
