【Abstract】 AC drives based on full digital control have reached the maturing status with the recent development of computer and DSP (Digital Signal Processing) techniques. In this paper a scheme of flexible control system of IM is proposed. This system is independent of the hardware, software structure, has the ability to extend and adapt to varying requirements. The work concentrated mainly on the algorithm simulation, hybrid simulation and realizing of the dual CPU control system. The core of the control system is a Host PC and a TMS320C30 DSP developing board. User interface, PWM pulse generation, A/D data acquisition and DSP control are all done by a Host PC. DSP deals with control algorithm, parameter estimation and state observation. Based on I/O data streams, the digital implementation of hybrid simulation is the key feature of the system. The performance of the real time system is reported when implementing an AC induction motor.更多还原
