Clamping with speed-variable maximum deceleration in the case of application of the random pwm - switching with a variable delay

摘要

A control system and a method for using the same for an electric machine with a random number - generating module, the a random number, which, in the region between a first value and a second value, is generated, a multiplier module, which the random number with a sampling rate multiplied, in order to generate a random delay value, and a deceleration limit module, the random delay value as a function of the rotational speed of the electrical machine is limited, and a limited deceleration value is generated.
