摘要： The present invention relates to a method and a device for executing phase compensation in a control system of a motor-driven vehicle, in which the time derivative for an output signal (y) from a circuit (1) contained in the control system is limited relative to the time derivative for an input signal (u) to the circuit (1) if the time derivative for the input signal (u) exceeds a predetermined value. An error signal (&egr;) is formed between the output signal (y) and the signal (x) present in the circuit (1), the time derivative of which is not limited in relation to the time derivative for the input signal (u). The error signal (&egr;) is filtered via an asymptotically stable filter (3) to form a signal (&dgr;), which is fed back and subtracted from the input signal (u) of the circuit (1) to form the signal (x). A conventional rate limiter may be used to form the output signal (y) from the signal (x).

摘要： A method and apparatus for correcting DC offset in a frequency to voltage converter. An analog frequency to voltage converter receives a frequency signal and outputs a voltage signal having a level that is indicative of the frequency of the frequency signal. The frequency signal is also input into a digital processor which converts the frequency signal into a reference signal that is fed back and summed with the voltage signal. The processor integrates the difference between the reference signal and the output signal to drive the output signal to be equal to the reference signal thereby nullifying DC offset in the output signal. The invention can be applied to controlling the DC bus voltage in a variable frequency AC drive.

摘要： The present a step controller includes a switching circuit having at least two outputting states, especially a three-level switch (DPS1) with negative feedback, and a PI or PID controller having an integrator (I1). The integrator is inactive during the positioning pulse of the three-level switch. The integrator (I1) is provided with a correcting element (CORR) which reduces the reset time (Tn) for a large input signal (xd). In this way, linear behavior of the step controller can be attained over the entire positioning range of a positioning element.
