| 摘要 |
The invention relates to a control system for an alternating current motor such as a polyphase induction motor. The control system includes a DC to AC inverter in combination with voltage and frequency regulators with the voltage and frequency being dependent upon each other. Control means are provided which sense the inverter current and translate the data sensed into two voltages which are separately subtracted from the output of the voltage regulator to provide two corrected voltages for regulating the voltage regulator and the frequency regulator.
