The main objective of the idle speed control is to maintain the idling speed at 650rpm and to reject as quickly as possible the extra load exerted on the engine system during idling mode. Comparing the three methods, it shows that PID tuning by ILA produced better results than heuristic tuning and pole placement.
ISC (Idle speed control) atau disebut juga IAC (Idle air control) merupakan suatu rangkaian elektronika yang digunakan untuk mengatur banyak sedikitnya udara yang melewati idle port ketika katup gas dalam posisi tertup atau tidak diinjak pedal gas.
Fluctuating Idle Speed Your vehicle's idle control valve is supposed to keep everything smooth when idling, so it makes sense that if it's acting up, your idle speed is going to fluctuate. While it depends on what's wrong with the valve, a fluctuating idle speed is one of the most common symptoms.

The idle speed control mode is used to prevent engine stall during idle. The goal is to allow the engine to idle at as low an RPM as possible yet keep the engine from running rough and stalling when power-consuming accessories, such as air-conditioning compressors and alternators, turn on.

An idle air control actuator or idle air control valve ( IAC actuator / valve) is a device commonly used in fuel-injected vehicles to control the engine's idling rotational speed ( RPM ). [1] In carburetted vehicles a similar device known as an idle speed control actuator is used.

The Idle Control function allows your ECU to control the engine idle speed. There are multiple ways this is achieved with either Drive-By-Wire (DBW) control, a Bypass Air Control (BAC) solenoid with either two or 3 wire types, or via a Stepper Motor system.
What is idle speed control system? The idle speed control mode is used to prevent engine stall during idle. The goal is to allow the engine to idle at as low an RPM as possible yet keep the engine from running rough and stalling when power-consuming accessories, such as air-conditioning compressors and alternators, turn on. 06c2Vh.
