IPC: H02N2/00
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To enable control with good responsiveness and without causing oscillation from a high revolution to low revolution by providing a driver with a gain variable means for changing the feedback gain, based on the output of a velocity detection means as a drive control means. SOLUTION: A microcomputer 108 reads in the count value from a counter 107, and computes the present number of revolutions, and compares it with gain switching reference number of revolutions. Then, it computes the drive frequency by the present sampling, using an error gain which has been decided, and outputs the D/A conversion data based on this to a D/A converter 105. Lastly, it controls the feedback gain, using the drive frequency computed this time for the next sampling. As a result, the number of divided error gains is increased on the basis of the number of revolutions, and the error gain can be decided from a high revolution to low revolution, and also in case that the response of an oscillatory motor has changed, system is capable of coping it.

Title: Calculating method for phase difference theta
Inventor: KAMIYAMA MASAAKI
IPC: G01R25/00
Filed: 1987-07-08
Abstract: PURPOSE:To improve calculation accuracy by calculating a phase difference thetabased on costheta and sintheta, and using a cos system or a sin system properly according to the error of the phase difference theta is large or not. CONSTITUTION:The output voltages v1 and v2 of primary-side and secondary-side input transformers 6 and 7 are stored in a RAM 15. Then a CPU 14 calculates costheta from the output voltage v1 and v2. Then whether the error of the phase difference theta is large or small is checked from costheta. When small, the phase difference theta is found from costheta in a data table in a ROM 18. When the error of the phase difference theta is large, on the other hand, the CPU 14 calculates sintheta from the output voltage v1 and v2 and searches the data table in the ROM 18 for the phase difference theta, calculating the phase difference theta. Thus, the cos system or sin system is used properly to find the phase difference theta with high accuracy.
