    摘要: A control apparatus capable of ensuring high control accuracy even if a controlled object is in a transient state, when a control input is calculated based on a value obtained by correcting a value calculated by a feedforward control method using a value calculated by a feedback control method. The control apparatus calculates a fuel correction coefficient such that an output from an oxygen concentration sensor converges to a target output, and multiplies a basic injection amount by the coefficient to calculate a fuel injection amount. The basic injection amount is selected from three values according to the cause of a mapping error. Two of them are calculated by searching respective maps according to corrected throttle valve opening values and engine speed. The other is calculated by multiplying a value obtained by searching a map according to the opening and the speed by a correction coefficient.

    摘要: A control apparatus which is capable of ensuring both high-level stability and accuracy of control and reducing manufacturing costs thereof and computation load thereon, even when controlling a controlled object having extremal characteristics or a controlled object of a multi-input multi-output system. The control apparatus is comprised of an onboard model analyzer and a cooperative controller. The onboard model analyzer, based on a controlled object model defining the relationships between an intake opening angle and an exhaust reopening angle, and an indicated mean effective pressure, calculates first and second response indices and indicative of a correlation therebetween, respectively. The cooperative controller calculates the intake opening angle and the exhaust reopening angle with predetermined algorithms such that the indicated mean effective pressure is caused to converge to its target value, and determines the increasing/decreasing rate and the increasing/decreasing direction of the aforementioned angles according to the first and second response indices.

The ECU calculates an FF injection amount with a predetermined feedforward control algorithm, and adds the FF injection amount to the FB injection amount, to thereby calculate a urea injection amount.
