Abstract:
A comparative study on vector controlled Permanent Magnet Synchronous Motor (PMSM) drive with Proportional-Integral (PI) speed controller for long cable implementation. As reported by previous research, long cable caused an over voltage problem at motor terminal and could be double from the pulse output voltage at inverter terminal. However, this paper addresses another important application issue, namely increased losses in the motor drive system caused degrade and instability of the speed performances when long cable lengths are required. Two different length cables which are 1 meter and 10 meter connected from dSPACE to PMSM and the results are compared and evaluated. A DS1103DSP embedded with the Real-Time Interface (RTI) provided by dSPACE, hysteresis current controller scheme and PI control has been developed for a high performance control for PMSM drives The robustness of different length of cable over load disturbance, step response and change at command setting with inertia variations are studied.
