WebNov 3, 2014 · A modern EMS is comprised of a large number of subsystems, and not only controls basic EMS-functions such as injection and ignition timing or emission control (i.e. Lambda closed loop control or catalyst heating) but also manages additional functions, such as continuous camshaft control, resonance flap actuation or engine fan control. WebThe lambda tuning for a second-order-plus-dead-time response will be covered in future articles. Procedure. The lambda tuning method for self-regulating processes involves three steps: Identify the process dynamics. Choose the desired closed loop speed of response, lambda. Calculate the required PID tuning constants.
