摘要： A method for controlling an electric motor by using the PWM technique including the steps of: applying to the clamps of the electric motor an electric voltage varying in time, which displays a square waveform and consists of a sequence of pulses having a uniform wave period and a variable width; adjusting the average value of the electric voltage by varying the width of the pulses; determining the overall required width variation; subdividing the overall required width variation in a determined number of partial variations, the overall sum of which is equivalent to the overall required width variation; and gradually varying the width amplitude of the pulses of the electric voltage by applying in a sequence a corresponding partial variation to each pulse, so that the difference between the width amplitude of a pulse and the width of a following pulse is equivalent to the corresponding partial variation.

摘要： A method for control of an injector in an internal combustion engine in which for a specific engine cycle, a control unit calculates a desired value of the opening time of the injector and forwards this desired value to a drive circuit of the injector, a supervision device calculates an actual value of the opening time of the injector during the injection phase, compares this actual value with the desired value and generates an error signal if the difference between the desired value and the actual value is outside a predetermined acceptability range.
