The paper presents sensorless state-space control of two-inertia drive system with resilient coupling.The control structure contains cyspera cream where to buy an I+PI controller for load speed regulation and a state feedback controller for effective vibration suppression of the elastic coupling.Mechanical state variable of two-inertia drive are obtained by using a linear minimum-order (Gopinath) state observer.The design of the combined (I+PI and state feedback) controller is achieved with the extended version of the modulus criterion [5].The dynamic behavior of presented control structure has been examined, for different wella color touch 77 45 conditions, using MATLAB/SIMULINK simulation.
