In the integrated power system ,the electrical propulsion system generally runs in the mode of constant power and presents negative characteristics .It seriously impacts IPS′s stability .Tradi-tional measure such as adding bus capacitance can improve its stability ,however ,this has the disad-vantage in that very large physical size ,weight and low economy .A DC link stabilizing control algo-rithm is proposed by the research of traditional propulsion driver control method .The principle and performance of the control algorithm are analyzed and simulated .The results show that the negative impedance effect of the propulsion system is dramatically diminished and the positive damper of IPS is provided sufficiently by selecting proper control parameters .
