摘要： A control system for a plant includes a sensor for detecting an output from the plant, an adaptive controller for controlling a manipulated variable applied to control of the plant in a manner such that an output from the sensor becomes equal to a desired value, and an adaptive parameter-adjusting device for adjusting adaptive parameters used by the adaptive controller. The adaptive controller is configured in a manner adapted to a predetermined dead time shorter than an actual dead time which the plant and the detection means possess. Sampling timing of an input vector input to the adaptive parameter-adjusting device corresponds to the actual dead time.

摘要： There is provided an air-fuel ratio control system for an internal combustion engine installed on an automotive vehicle. The control system controls the air-fuel ratio of a mixture supplied to the engine to a value leaner than a stoichiometric air-fuel ratio immediately after the start of the engine. Operating conditions of the engine and/or operating conditions of the automotive vehicle is detected. Starting of the vehicle is predicted based on the detected operating conditions of the engine and/or the detected operating conditions of the automotive vehicle. The air-fuel ratio of the mixture supplied to the engine is changed to a richer value than the leaner value when the starting of the vehicle is predicted.

摘要： A fuel metering control system for an internal combustion engine, having a feedback loop. In the system, the quantity of fuel injection (Tim) to be supplied to the engine (plant) is determined outside of the feedback loop. A feedback correction coefficient (KSTR) is calculated using an adaptive controller and a feedback control is carried out by multiplying the quantity of fuel injection by the coefficient in the feedback control region. In view of the situation, once leaving the feedback control region due to, for example, fuel cutoff, but soon returning to the feedback control region shortly, internal variables of the adaptive controller necessary for coefficient calculation are held so as to make it unnecessary to determine the variables and to keep the control continuity and to enhance the controllability. On the other hand, if it takes a longer time to return the region, the variables are set to initial values.

摘要： A cylinder-by-cylinder air-fuel ratio-estimating system for an internal combustion engine includes an air-fuel ratio sensor arranged in the exhaust system of the engine, at a confluent portion of the exhaust system. The air-fuel ratio of a mixture supplied to each of the cylinders is estimated based the output from the air-fuel ratio sensor, by using an observer for observing the internal operative state of the exhaust system based on a model representative of the behavior of the exhaust system. The air-fuel ratio at the confluent portion is estimated by using a delay parameter representative of the response delay of the air-fuel ratio sensor, and the air-fuel ratio of the mixture supplied to each of the cylinders is estimated by using the estimated air-fuel ratio at the confluent portion. The estimated air-fuel ratio of the mixture supplied to each of the cylinders is subsequently used for estimating a value of the air-fuel ratio at the confluent portion of the exhaust system.

摘要： An adaptive controller using an adjustment law expressed in recurrence formula, including a plant, a controller which controls an input to the plant, and a parameter adjuster which adjusts a parameter of the controller. In the controller, an input to the parameter adjuster is multiplied by a coefficient other than 1 such that the range of change of the parameter adjuster's internal variable is restricted to a predetermined limit. With this arrangement, the controller can be realized on a less expensive and fewer-bit-length microcomputer such as 16-bits. The input to the parameter adjuster may be made up of the control input to the plant and an output therefrom. Alternatively, the input to the controller and an output from the plant may be both multiplied by a coefficient other than 1 to be input to the parameter adjuster. Further, it may be arranged such that a gain matrix element of the parameter adjuster is intermittently replaced with a prescribed value when it exceeds a limit, or when the cycle of the control exceeds a predetermined number of cycles.
