A package for computer aided design of multivariable discrete control systems

TLDR: The package performs the following tasks: calculation of the equivalent z-transfer function of a continuous system, stability design; interaction improvement; operations with transfer functions matrices and simulation of closed loop discrete multivariable systems.

Abstract: In this paper, a package of programs for the computer aided design of discrete multivariable linear control systems is shown. It is based on frequency-domain techniques. Also, a new stability design method for multivariable systems is described. The package performs the following tasks: calculation of the equivalent z-transfer function of a continuous system, stability design; interaction improvement; operations with transfer functions matrices and simulation of closed loop discrete multivariable systems. The solution of these tasks leads to the manipulation of transfer functions matrices. It is carried out with the aid of the Graph Theory. A design example is included to illustrate the use of the stability design method and the efectiveness of the package.
