    摘要: A closed-loop feedback-controlled servo system is disclosed which reduces command-to-response error to the system's position feedback resolution least increment, .DELTA.S.sub.R, on a continuous real-time basis for all operating speeds. The servo system employs a second position feedback control loop on a by exception basis, when the command-to-response error .gtoreq..DELTA.S.sub.R, to produce precise position correction signals. When the command-to-response error is less than .DELTA.S.sub.R, control automatically reverts to conventional control means as the second position feedback control loop is disconnected, becoming transparent to conventional servo control means. By operating the second unique position feedback control loop used herein at the appropriate clocking rate, command-to-response error may be reduced to the position feedback resolution least increment. The present system may be utilized in combination with a tachometer loop for increased stability.

    摘要: A precision machining system for machining a workpiece into a desired surface with two tool driving units. A first drive unit moves the tool along at least two axes to shape the workpiece similar to a desired surface. A second drive unit moves the tool along one of the axes in a very finely controlled manner. A measuring unit measures the tool position with an accuracy higher than that to which the first drive unit can respond. A signal producing unit is responsive to the measuring unit for producing a control signal for controlling the operation of the second drive unit while the first drive unit is operating.

    摘要: The disclosure describes a digital servo control circuit to actuate an analog servo motor smoothly from an actual present position to a new desired servo position in response to digital information from a computer. The control circuit described receives from a computer digital information representative of a new position desired at a predetermined velocity rate. Such information normally is pre-timed to correspond with a preselected timing rate in the digital computer. A position signal generator is responsive to such pre-timed digital information to generate a predetermined number of position signals intermediate of the pre-timed digital information to achieve the desired smooth operation of the servo motor.

    摘要: A control system for positioning a control valve is disclosed. The control system employs first and second control loops, and a plug and seat valve assembly. The first control loop monitors a position or variable of the valve or device being controlled and compares it to a provided setpoint to generate a setpoint for the plug and seat valve. The second control loop compares the measured position of the plug and seat valve to the second setpoint to generate a correction signal to accurately position the plug and seat valve. By employing first and second control loops, the accuracy and responsiveness to which the control valve is positioned is improved.

    摘要: A compensation design allows for use of a generic servoamplifier for multiple types of actuator Direct Drive Valves (DDV). Cost savings can be realized by using common electronics applied to multiple actuator types. The implementation allows for design of the compensation directly from experimentally or analytically derived frequency performance curves of the generic servoamplifier resulting in the performance comparable to a custom servoamplifier for the direct drive valves.
