Abstract
An adjustment control system compares multiple control amounts detected by a sensor with target values, thereby computing individual control amount deviations. When at least one of the control amount deviations is out of a predetermined tolerance, an operation-amount-determining section determines operation amounts for compensating the control amount deviations. When successful instances that have been used in the computed control amount deviations are available, the operation-amount-determining section executes a learning-control method that determines the operation amounts according to the control instances. When the successful instances are not available, the operation-amount-determining section executes an adaptive-control method and thereby determines the operation amounts. As a result of the execution of the learning-control, when the control amount deviations are not converged into the tolerance, the operation-amount-determining section determines the successful instances used in the control to be inappropriate. Then, the operation-amount-determining section switches from the learning-control to the adaptive-control, thereby executing adjustment control. In this case, inappr…
