摘要： PROBLEM TO BE SOLVED: To provide a method of estimating the speed of an induction motor and the magnetic flux of a rotor.
SOLUTION: This method includes a step (a) of obtaining a freely measurable or calculable variable for estimating the speed of the induction motor and the magnetic flux of the rotor, a step (b) of calculating a parameter as the counter electromotive force of the motor induced by the variable obtained in the step (a), and a step (c) of estimating the speed of the motor by using the parameter calculated in the step (b), its estimate, and the variable obtained in the step (a). This method also includes a step (d) of estimating the magnetic flux of the rotor by using the estimate of the speed estimated in the step (c) and the parameter calculated in the step (b). Consequently, the computational quantity can be reduced, because estimation algorithm can be performed by using a smaller number of computational formulae for the case where a whole dimensional observation instrument is used as in the conventional case and a sensor-less speed control system for induction motor which is excellent in low-speed characteristic, is stable over a wide region, and has a quick speed response characteristic can be embodied easily.

摘要： PURPOSE:To enhance the responsiveness of controlling an AC power source by detecting the rate of change of the output current command value and altering the gain of a feedback system in response to the rate of change, thereby automatically controlling the controlling and responding characteristics in response to the rate of change of the output current command value. CONSTITUTION:Main switching elements 2A, 2B are PWM-switched in response to the error signal which is obtained from an error amplifier 7 as the difference between the output current command value and the output current detection value, thereby controlling the feedback so that the instantaneous value of the output current supplied to a motor converges to the instantaneous value of the output current command value. Further, a multiplier 15 is provided, and the amplitude of a carrier signal which is inputted to a comparator 9 is varied in response to the control signal by the multiplier 15. As a result, the PWM operation which is performed by the comparator 9 with the error signal as a modulation input signal is performed on the basis of the carrier signal which is varied in amplitude by the control signal.

摘要： PURPOSE:To stably control an induction motor by controlling the frequency of an inverter based on a signal added with a slip signal to the output of a speed detector and correcting the slip signal based on the temperature of the motor. CONSTITUTION:An inverter 6 applies an AC power source voltage of a variable frequency to an induction motor 7.

The output of the detector 8 is added to the slip signal, the output is applied to the inverter 6 through a voltage/frequency converter 14 and an AC voltage generation controller 15, thereby controlling the frequency of the inverter 6. The temperature of the motor 7 is detected by a temperature detector 17, and the slip signal is corrected by the detected output.
