Performance optimizing control system for an internal combustion engine

摘要

To match the control adjustment speed of an internal combustion engine control system to operating speed thereof, a control loop is provided which includes an operating parameter sensor, a correlator comparing a sensed signal with an oscillating command signal, a controller responsive to a consequent error signal and which then controls operation of the engine; a speed transducer provides speed- dependent output signals which control (a) the frequency of oscillation of the oscillator and (b) the operating speed of the controller. If the controller is an integrating- type controller, then the time constant of the integrator thereof is changed, for example by varying a resistance value of an R/C circuit as a function of engine speed.
