Popis: Publisher Summary This chapter discusses the necessary and sufficient conditions of parametric invariance. In the paper of H Ur and J.Truxal the problem of compensating the effect of small parameter variations is considered. This problem can be solved for arbitrary parameter variations. The problem of parametric invariance for linear system subject to stationary or nonstationary variations B(t) of matrix A has a solution in the form of a system of vector equalities. It is observed that for the realization of the condition of parametric invariance it is necessary to adjust simultaneously the elements of matrix B. It is found that such an adjustment, for example, can be achieved by measuring the plant variations and effecting appropriate compensation by adjusting the controller parameters.
