    摘要: Disclosed herein is a motion monitoring system for monitoring movement of a brush-type DC motor. The system includes an electrical comparator having first and second differential inputs. A current detector is connected to provide a drive current signal to the first differential input of the comparator. A low-pass filter is connected to provide an averaged drive current signal to the second differential input of the comparator. When a drive current is applied to the motor, the comparator produces a stream of binary logic-level pulses corresponding to motor movement. The pulses can be used to determine motor position and velocity.

    摘要: A microprocessor may include a logic circuit for executing instructions of a data processing application. The microprocessor may have a timer system which includes a clock counter connected to a clock input for receiving a clock signal and counting a number of cycles of the clock signal. A clock comparator may be connected the clock counter and to a timer register in which a timer reference value can be stored. The clock comparator may compare a number of cycles of the clock signal with the timer reference value and generate a timer signal based on the comparison. The timer system may have a timer output for outputting timer signal. The timer system may include a control input for receiving a digital value representing a measured value of a sensed parameter of a device and a control register in which a control reference value can be stored. A control comparator may be connected the control input. The control comparator may compare the digital value with the reference value and generating a device control signal based on the comparison. The timer system may have a control output for outputting the device control signal to an actuator arranged to control the parameter of the device.

    摘要: Disclosed is a servosystem including a servo motor which shaft is positioned in response to digital command signals. A comparator or error generator produces a pair of digital output signals respectively representative of an error magnitude and direction signal necessary to rotate the shaft in the desired direction to reduce the error, the digital output signals being converted to a bidirectional analog signal which is combined with a time derivative signal, the resultant signal being applied to the servo motor. Also disclosed are novel comparator means having gating circuitry necessary to assure that the minuend signal is always greater than the subtrahend signal, a digital to analog convertor means effecting a unidirectional to bidirectional analog conversion, and novel compensation network for combining an error analog signal with a velocity analog signal.
