Sažetak
This paper presents the design of a controller for a bidirectional DC-DC converter for speed control of a permanent magnet DC machine (PMDC). In recent years, this electric drive system has often been used in electric vehicles or hybrid electric vehicles. In this application, the development of a controller is required to support the various functions of the machine. The design methodology of the controller should provide satisfactory dynamic performance under both motor and generator operation of the PMDC machine. In this regard, the control of the bidirectional DC/DC converter is necessary. From the perspective of speed control, the condition for absolute stability is derived from the small-signal model of the PMDC drive system. Then the Ziegler-Nichols tuning table is used to determine the gain of the proportional-integral (PI) controller in the conventional way. From further investigation, it was found that the transient response and stability margin of the speed control loop in the conventional case are
