| Abstract |
This paper deals with the control of a buck converter. The 120 kW converter is fed by a varying 1500 V DC supply. Digital voltage as well as current control is discussed. A discrete linearized state space model is derived. A controller structure is chosen and the linearized model is extended with the controller states. For this extended model an optimal output feedback gain is computed by means of an LQ-algorithm. Digital simulation results are compared with full scale test bench measurements. |
