This paper describes an absolute stability analysis of idle speed control systems. Current idle speed control systems make use of both spark advance and the idle air actuator to control engine speed for improved response relative to variations in the target idle speed due to load disturbances. The control system at idle can be presented by a multiple input multiple output (MIMO) model [1]. Control system design is usually done based on linear or linearized models [2,3,4]. However idle speed control systems are nonlinear because of the saturation of the actuators. This paper describes an application of the absolute stability theory to idle speed control systems with saturation of actuators.
