The study of cross coupling compensation considering the infuence of controller´s discrete nature

This paper presents the impact of sampling control signals and cross coupling compensation in the active rectifier converter. The relations describing the nature of the influence of the compensation effects considering the features of a digital implementation of the control system were derived. Frequently, in the many others studies a closed-loop system with the compensation of the cross coupling are described without detail analysis of real characteristics in a digital implementation. The ratios obtained show that in view of the discrete functions properties the dynamic properties in terms of the independence of the two control vector components depend on the period of digitization and delay required by the calculation process. As an example, the results of simulations show that the static characteristics are improved in case of the compensation is used. The expediency of application in a strong degree depends on the computing facilities of a digital controller.
