    摘要： A brushless DC motor modifies motor commutation events to reduce noise by providing overlapping activation of the switch being deactivated with the switch being newly activated so that three switches are temporarily activated. The newly activated switch is pulse width modulated with a motor torque controlling duty cycle, and the switch being deactivated is pulse width modulated synchronously with the newly activated switch but with a duty cycle decreasing from the torque controlling duty cycle. The decreasing modulation of the switch being deactivated allows a slower current decrease in the phase turning off to reduce or eliminate the disturbances, and thus the noise. The decreasing modulation is preferably exponential in manner, with a time constant varying inversely with motor speed so that the duty cycle reaches a predetermined minimum in a predetermined maximum number of motor electrical degrees. The decreasing modulation may be switched on at low motor speeds where its noise reduction is required and switched off at higher motor speeds where the potential for interference with commutation is greater. The decreasing modulation is applicable in a dual switching mode in which each activated switch, except for the switch being deactivated in commutation, is pulse width modulated at the torque controlling duty cycle, or in a modified single switching mode in which the activated switch of one of the upper or lower groups is always closed continuously during its activation, except for commutation, during which the switch remaining on, which alternates between the groups, is closed continuously. Each mode of operation is applied in the motor speed/torque region to which it is best suited.

    摘要： A vehicle power steering system uses an electric motor to drive a pump at a variable speed to provide power steering fluid at a variable flow for power assist to operator steering efforts. The system has a speed control for the electric motor which derives a command speed signal from a power steering load signal, senses motor speed and controls electric power to the motor in response thereto to vary the speed of the electric motor in the direction of the command speed signal. In a switching region of the power steering fluid pressure signal, the speed control switches between a low speed for standby operation and a higher speed to supply the power steering operation demands. The speed control modifies the switch-point load value in response to the power steering fluid temperature sensor to compensate for temperature dependent losses. Separate switch-points are preferably provided for increasing and decreasing power steering load to provide hysteresis; and both switch-points are preferably compensated.
