摘要： A control system for a plant is disclosed. According to this system, a value of a switching function which is defined as a linear function of a deviation between the output of the plant and a control target value, is calculated. A reaching mode input is calculated. The reaching mode input contributes to placing a deviation state quantity which is defined based on the deviation, onto a switching straight line on which the value of the switching function becomes zero. The reaching mode input is corrected according to the value of the switching function. A control input to the plant is calculated with a response specifying type control, and the control input includes the reaching mode input. The plant is controlled with the calculated control input.

摘要： A system for discriminating degradation of an exhaust purification system of an internal combustion engine having an adsorbent installed at a bypass exhaust gas passage branched from an exhaust pipe of the engine, which is opened by a switch-over valve at starting of the engine to introduce the exhaust gas such that the adsorbent adsorbs unburned HC in exhaust gas generated by the engine and is closed such that the adsorbent desorbs the adsorbed HC and the desorbed HC is thereafter recirculated at a position upstream of a catalyst. In the system, an inflow amount and outflow amount of HC flowing in and out of the adsorbent are determined based at least on the engine operating conditions and the detected concentration of HC. Then, the ratio therebetween is calculated and compared with a threshold value and if the ratio is less than the threshold value, the adsorbent is discriminated to be degraded, thereby enabling to improve the discrimination accurately.

摘要： The temperature of an exhaust gas flowing through an exhaust passage 3 is estimated or detected, and the temperature of an active element of an exhaust gas sensor 8. (O2 sensor) is controlled at a predetermined target temperature by a heater using the estimated or detected temperature of the exhaust gas. For estimating the temperature of the exhaust gas in the vicinity of the exhaust gas sensor 8, the exhaust passage 3 extending up to the exhaust gas sensor 8 is divided into a plurality of partial exhaust passageways 3a through 3d, the temperatures of the exhaust gas in the partial exhaust passageways 3a through 3d are estimated successively from an exhaust port 2 of an engine 1. The temperature of the exhaust gas is estimated according to an algorithm which takes into account a heat transfer between the exhaust gas and passage-defining members 6a, 6b, 7 which define the exhaust passage 3 and a heat radiation from the passage-defining members into the atmosphere. A control input that is applied to the heater includes at least a component depending on the temperature of the active element of the exhaust gas sensor 8 and a component depending on the temperature of the exhaust gas. Even if the temperature of the exhaust gas changes, the temperature of the active element of the exhaust gas sensor 8 can be controlled stably at the desired temperature.

摘要： A control system for a plant is provided. This control system can control the plant more stably, when the model parameters of the controlled object model which are obtained by modeling the plant, which is a controlled object, are identified and the sliding mode control is performed using the identified model parameters. The model parameter identifier (22) calculates a model parameter vector (θ) by adding an updating vector (dθ) to a reference vector (θbase) of the model parameter. The updating vector (dθ) is corrected by multiplying a past value of at least one element of the updating vector by a predetermined value which is greater than “0” and less than “1”. The model parameter vector (θ) is calculated by adding the corrected updating vector (dθ) to the reference vector (θbase).
