| Abstract |
The essence of the paper is an approach to the control of electromechanical system with resilience between motor and load. The servo drive, equipped with a PM synchronous motor and current controlled VS inverter, was tested using simulation model. Improving of the damping properties of the system, by means of state controller optimization method, was the goal of investigations. Two control structure were studied: a linear one, with constant parameters, and a nonlinear, with parameters depending on speed error. The optimization method is based, on quality criterion and the Simplex procedure. The simulation results indicate the effectivnes of nonlinear state controller assuring good damping properties of the electromechanical system. |
