Title: Control device of rotating electric machine
Inventor: MINAGAWA YUSUKE
IPC: H02P6/08
Filed: 2000-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent the characteristics of a magnet from deteriorating due to demagnetization in a coil where the magnetic fields with the same polarity of the magnet face each other by decreasing the peak of the control current of the coil while the magnetic fields of the magnet face each other. SOLUTION: Even while one entire pole of a first rotor 3 opposes the same type of pole of a second rotor 4, namely a magnetic flux flowing out of a magnet for composing one pole of the first rotor, or a magnetic flux flowing into the magnet drastically decreases to allow the operating point of the magnet to approach a demagnetization region, the density of the magnetic flux passing through the magnet is increased by a correction current, thus avoiding the entry of the operating point of the magnet into the demagnetization region and suppressing the deterioration of the characteristics of the magnet.

Filed: 2000-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a control system that forms a vibration control loop of an active vibration resistant device not for each conventional mode of motion but for each mode of vibration, and establish a calculating method that shortly and precisely obtains a mode matrix ϕ. SOLUTION: The method on a time-responsive basis acquires time-responsive waveforms of all acceleration sensors obtained when a vibration-resistant table is slantingly vibrated by a pseudo impulse (step S802). The time-responsive waveforms are frequency-analyzed (step S803) to compute a mode matrix ϕ(step S804), which is used or implemented in the vibration mode-based noninteracting control system (step S805). The method on a frequency-responsive basis sweeps a sinusoidal wave in a combination of axes for vibrating the vibration-resistant table slantingly to acquire frequency responses down to all the acceleration sensors. The acquired frequency responses are plotted on a Nyquist diagram to compute parameters for each circle, which are used as ϕ. The obtained ϕ is implemented in the vibration mode-based noninteracting control system.
