摘要： The invention relates to a method for positioning a pen in a recording device for recording the time profile of a measurement signal which can be connected. In order to implement the highest possible mapping accuracy of the measurement signal onto the recording signal at a low cost and with DC isolation between the measurement signal and drive means of the pen, it is proposed that the positioning error (300) be phase-width modulated, the pulse-width-modulated positioning error (400) be transmitted in a floating manner to a signal converter (70), and a control voltage for the electric motor (90) be determined using the signal converter (70) from the pulse-width-modulated positioning error (400) by normalizing the difference between the pulse duration and the pulse-pause duration, via the sum of the pulse duration and the pulse-pause duration.

摘要： Method and apparatus for robust integral-pulse control of servodrives of unknown dynamics. According to the current value of the controlled object position, a microprocessor controller presets the current values of pulse duration and pulse amplitude as functions of the position control or velocity control error. The current value of the pulse period is a function of the sum of (difference between) the current values of orthogonality and robustness parameters when the object moves with acceleration (when the object moves with deceleration). The orthogonality parameter is calculated in proportion to the current value of pulse duration under the condition of orthogonality of the adjacent pulses and the Indeterminacy Principle. The robustness parameter is a function of the current object acceleration/deceleration. Throughout each control period, additional modulations of pulse amplitude and pulse duration are employed whose frequencies are preset by a microprocessor controller for each control period as functions of the controlled object's current acceleration/deceleration and which are limited by these parameters' values in the current and previous control periods calculated as functions of the position control or velocity control error. The modulation steps of the pulse amplitude and pulse duration derived from additional modulation are calculated in proportion to the difference between the current position value of the controlled object and this parameter's value in the previous control period. The microprocessor outputs codes of current values of pulse amplitude, duration and period and transmits them to the amplifier. The pulse sequence is performed and applied to the electromotor.

摘要： A closed-loop PWM current control for force motor applications in which temperature induced impedance variations are compensated for without adversely affecting the transient response of the control. In generating the force motor PWM duty cycle, the control employs a digital integration of the sampled current error which, in addition to the usual pole, creates a zero which tracks and cancels the force motor pole. As a result, the undesired transient response characteristic associated with the interaction between the filter and force motor poles is avoided. The gain coefficients employed in the filter are chosen in relation to a measure of the force motor temperature so that the cancellation occurs throughout the range of expected temperature variation. Since the force motor is submersed in the transmission fluid, the temperature of the force motor is accurately represented by a measure of the fluid temperature.

摘要： A linear servoactuator including an integrated split-secondary differential transformer position sensor and a fluid driven linear actuator controlled by solenoid poppet valves. Signals from the position sensor transformer are digitized and linearized by a control microcomputer by using digitized transformer signals as addresses for a programmable read only memory. The linearized output is compared to a command position to determine an error value. When the error reaches a predetermined magnitude, indicating that the actuator is approaching the command position, solenoid poppet valves are actuated by a pulse-width modulated signal from the microcomputer to progressively decrease the fluid flow to the actuator for deceleration.
