Abstract: The solution involves the use of two or more motors to drive a common mechanism. The single control loop includes a position sensing device coupled to only a first of the plurality of servo motors and generating a position signal. A signal comparator receives the position signal and compares the position signal with a predetermined desired position based on a desired motion profile. The difference from the actual position and the motion profile is output as a position error signal. A signal converter receives the position error signal and derives a conversion signal based on the error signal. The conversion signal is provided to a plurality of signal amplifiers, which in turn are coupled to the plurality of servo motors. The amplifiers provide power to the motors for driving the mechanical load.

Abstract: A fan controlling system applicable in an electronic system having a plurality of fans is disclosed. The fan-controlling system includes a first signal generating module and a second signal generating module for generating a first and a second pulse width modulation (PWM) signals according to control instructions output by the electronic system. The fan-controlling system further includes a phase-inverting module and a delay module. Therefore, PWM signals, which are delayed with a time interval one another, can be generated by the fan controlling system, so as to respectively control a plurality of fans of the electronic system, thereby avoiding the peak value of the total power signals when the fans are run from increasing instantly, and power signal for supplying the electronic system from decreasing instantly, making the electronic system run abnormally, and its stability becomes worse.

Abstract: A control device measures time intervals T1 to T12 from the reference time until when each of the rotational angles θbn1, θbn2 output from each of resolvers becomes n×60 degrees (n=1 to 12, i.e., 60 degrees to 720 degrees). Then, the control device calculates a deviation angle Δθn at each of the rotational angles at the intervals of 60 degrees by calculating T1/T12 to T11/T12 using the measured T1 to T12. By substituting the calculated deviation angle Δθn into an equation, n×60°+Δθn (n=1 to 11), the control device corrects the rotational angles at the intervals of 60 degrees. The control device generates each of drive signals DRV1, DRV2 using each of the corrected rotational angles, and outputs each of the drive signals DRV1, DRV2 to each of inverters. The inverters drive each of AC motors (M1, M2) based on each of the drive signals DRV1, DRV2.

Abstract: Two windshield wiper blades are powered by separate electric motors. The blades overlap and when one blade is at its reversal point the other blade leaves part as the other blade begins to return to park. The position of the blades is encoded. The blades, if synchronized should be at identical locations and position codes at the same time. Motor power to the blade that arrives first is be removed, allowing the blade to coast. If the other blade still does not arrive at the position after an elapsed time, the first to arrive blade is dynamically braked. Intermittent wiper operation is provided in a way that initiates an immediate wipe if wiper delay is changed while the blades are parked.
