    摘要: A stepper motor system and apparatus use a position-feedback device, which may have a resolution capability as low as 200 counts per motor shaft revolution, for misstep detection and motor step recovery. In use of the system, position deviation is computed periodically and cyclically, by subtracting the feedback position from the corresponding commanded position, to determine the load angle, implicitly, and the operating status of the motor. If the load angle is within an established allowable range of values, normal stepper operation along the programmed trajectory is maintained, without adjustment. A load angle that exceeds the limits of that range however indicates that a misstep has occurred, and the system controller initiates immediate action to recover lost motor steps, to reestablish synchronism, and to then continue toward the final target position, with minimal loss of time.

    摘要: A stepping motor includes two coils. A driver circuit drives the stepping motor by setting dissimilar phases of supply currents to these two coils. One terminal of one coil is connected to ground and another terminal is set to a high impedance state, and an induced voltage generated at that coil is detected as a voltage with respect to ground. Then, in accordance with the state of the detected induced voltage, the magnitude of motor drive current supplied to the two coils is controlled.

    摘要: A software compensation command is generated to command a linkage to move an end body in a work space. A manipulator Jacobian is computed given a nominal linkage command; and a normalized Jacobian is computed from the manipulator Jacobian, a joint space normalizing matrix Q, and an error space normalizing matrix E. The normalized Jacobian and the Q and E matrices are used to produce the software compensation command.

    摘要: An automation system for programming appliances having programmable controllers, programmable devices and trigger devices that communicate over a communication link. The user programs the programmable devices by placing the programmable controller in its training mode, activating the trigger device to generate a trigger signed and places select programmable devices in their programmed state. After all of the desired programmable devices have been put in then programmed states, the user takes the programmable controller out of its training mode. When the programmable controller is out of its training mode, it monitors the communication link for the trigger event. Upon detecting the trigger event, the programmable controller sends messages to the selected programmable devices instructing them to go to their programmed state.
