| 20080314367 | Control system using pulse density modulation - A method for modified pulsed control of an electromechanical actuator in accordance with the invention comprising the steps of a) setting a common time length for all of the pulses in a pulse train, and b) varying (modulating) the number of such pulses per unit time (repetition rate) by varying the length of time between pulses in the train. Such control is defined herein as pulse-density modulation, or PDM. Especially in applications having a relatively low percent duty cycle if controlled by the prior art Pulse Width Modulation (PWM), PDM control results in more accurate control of an actuator, with higher resolution. The method is especially useful in controlling flow of a fluid, through a valve, such as a fuel injector, and especially at relatively low flow rates at high supply pressures P | 12-25-2008 |
