Modelling application of LQG-LTR for idle speed control

الملخص EN

This paper describes engine model at idling speed and this is then applied to idle speed control of a four-cylinder electronically fuel injected spark ignition engine.

The process model for an internal combustion engine with spark ignition is inherently non-linear.

For the purpose of control analysis, a linear model is developed[14].

The control technique applied to the engine is linear-quadratic Gaussian and loop transfer recovery method (LQG / LTR).

Computer simulation is used to illustrate the performance of the control system
