In spite of various attempts and proposals devoted to the creation of the syntbesis method of multivariable linear control systems there is still a Jack ofrelatively simple engineering method which could be compared to the well-known methods being applied to the single-input - single-output systems. The object of the paper is to present a new proposal concerned with such a method for multiinput - multioutput systems based on the frequency response approach. Assuming the controller of the diagonal form the aim of synthesis is to ensure the system stability and sufficiently small steady-state control errors in each loop (or sufficiently large disturbance dampings in the system) over the prescribed frequency band. The idea of the method proposed is to divide the system into a number of noninteracting loops equivalent to the system under consideration and then to synthesise them independently by means of simple, well-known frequency metbods. It has been proved tbat the control system synthesized in this way may, under some conditions, have better performance than the noninteracting system.
