摘要： An electrical control system includes multiple frames of reference in the error path of a controller. In each such frame, a particular chosen component of the error vector appears as a constant vector and is passed through a pure integrator thus acquiring infinite gain. In the steady state, the net error vector can then be forced to have zero content at each of the targeted frequencies (as set by the rotational velocity of the frames of reference). Both parallel and series configuration of the controller are provided, as well as the control methods used by the controllers.

摘要： A control system comprising a gain control circuit for adjusting the gain of an input signal to provide a gain controlled signal and an integrator for integrating the gain controlled signal to provide an output signal. A first circuit responds to a particular condition for changing the gain of the gain control circuit and a second circuit responds to that same condition for changing the output signal independently of the gain control signal to bring about a more rapid change in the output signal than could be brought about solely by changing the gain controlled signal.

摘要： In the design of a mechanical component for a mechanical device driven by a feedback controlled electric motor, the user is enabled to easily know how the properties of mechanical component affect the generation of abnormal vibrations of the mechanical device. In a design assist apparatus (1), the processor (11) is configured to set a plurality of parameters of a mathematical model of an analysis target component selected from one or more mechanical components (24, 56, 58) forming the mechanical device, compute a pole of a transfer function of the mechanical device associated with one or more vibration modes of the mechanical device according to the parameters, and create a stability determination diagram including an isoline of a real part of the pole of the transfer function.

摘要： The input to an integrator is controlled by a logic circuit to reduce tracking errors caused by changes in acceleration. In one embodiment, the logic circuit obtains the derivative of the input signal and multiplies it with the input signal. The input signal is fed to the integrator through a switch which is closed when the product of the input signal and its derivative is positive, and which is open when the product is negative.

摘要： The time constant of an electronic integrator is made variable by inserting a pulse controlled FET switch in series with the input resistance. This integrator is used to generate the integral and derivative terms in an electronic process controller so that the time-constants of those terms may be varied remotely by a series of pulses or by a voltage that controls a pulse generator. An amplifier whose gain is made variable by alternately shorting the gain to zero with a switch controlled by a series of pulses is used to provide adjustable gain of the proportional band circuit in the controller. These circuits are also used in a lead lag unit.

摘要： In the present invention, an input-side control device generates an input-side torque command signal Tr using an engine torque command signal, an input-side velocity detection signal ω, and an input-side shaft torque detection signal Tsh, and is provided with: a shaft torque controller that generates a torque command signal on the basis of the engine torque command signal and an input shaft torque detection signal; and an inertia compensator that feeds back an inertia compensation signal generated by multiplying a set inertia value Jset by the input-side velocity detection signal. The shaft torque controller is provided with a first low-pass filter that, from the engine torque command signal, allows a high-frequency component to decay; and the inertia compensator is provided with a second low-pass filter that, from the input-side velocity detection signal, allows a high-frequency component to decay.

摘要： Automatic Process Control Device having input transistors to receive process and set point signals; a subtractive amplifier to compare the process and set point signals and produce one of two amplified deviation signals which are limited to maximum values by zener diodes; capacitors to receive, time-integrate and store the amplified and limited deviation signals, and produce a neutral output if the time-integration of the amplified and limited deviation signals is in balance, and one of two trigger signals if the time-integration of the amplified and limited deviation signals is positive or negative; and relay switches connected to discharging circuits and in series with zener diodes to receive the trigger signals and operate a controlling device upon the process to urge the process toward its desired set point, and simultaneously produce a corresponding tripping signal which urges the capacitors toward a status to produce the neutral output, such that as the controlling device is operating upon the process the Automatic Control Device is simultaneously being urged toward its neutral position, and the response of the controlling device is time-integrated to the accumulative deviation of the process. In use, the disclosed Automatic Control Device virtually eliminates "hunting", and it can also accomodate and control extreme and sudden changes ("bumping") in either the process variable or the set point without damage to the Automatic Process Control Device or its operation.
