Design of asymptotically stable multivariable systems with a specified static accuracy

The paper is concerned with design of asymptotically stable linear multivariable control systems (MVCS) with state (state estimate) feedback. The structure of a closed-loop MVCS with rigid feedbacks of control variables and flexible feedbacks of plant state estimates is investigated as is the identifier structure which separate problems of insuring the desired static accuracy and of asymptotic stability of the designed system and eliminate the effect of the loop in which unmeasurable plant states are identified on the static mode.
