Title: Controller of camera
Inventor: HASHIMOTO ISAMU
IPC: G03B17/00
Filed: 1991-11-25
Abstract: PURPOSE:To reduce a rush current when a motor is energized and to prevent the runaway of a system caused by fluctuations in a power source by providing a means alternately switching energization and nonenergization so as not to overlap the energization of plural motors. CONSTITUTION:A mirror motor driver 33 controls the braking, backward and forward rotations, and nonenergization of a mirror motor 36 with a driving signal from a peripheral circuit 19 controlled by a central processing circuit 11. A film motor driver 34 controls the braking, backward and forward rotations, and nonenergization of a film motor 37 with the driving signal from the peripheral circuit 19, similarly. Further, when one motor is energized, the central processing circuit 11 alternately switches the energization and nonenergization so that the other motor is not energized. But, since the motor is continuously rotated with inertia even during the nonenergization, two motors can continue their rotations without any trouble, while repeating the energization and nonenergization.

Title: Control scheme for synchronous motor
Inventor: YAMAMOTO YASUHIRO
IPC: H02P21/22
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To solve problems that arise associated with convergence computation when d- and q-axis currents are determined based on only torque commands and voltage conditions in controlling IPM and problems of voltage saturation and magnetic saturation. SOLUTION: Q-axis current computation estimates from a magnetic flux table 11 a magnetic flux component corresponding to the current of a rotating coordinate system that rotates in synchronism with a field system, and an output torque computation part 13 estimates from a q-axis current and the result of the magnetic flux estimation a torque that is produced in this state of current. A torque current computation part 14 determines a q-axis current component that corrects the component of error between the estimated torque and a torque command so that the estimated torque is matched with the torque command, adds up the q-axis current component and the present q-axis current, and outputs the result as a new torque current command.  An inductance table 12 calculates self-inductance on the d-axis and the q-axis when the current of the rotating coordinate system varies, and uses it for q-axis current computation. In addition, a voltage saturation prevention controlling means is included which, if the output voltage is increased and exceeds a voltage limit value, produces a demagnetization current.
