Abstract: In an output controlling method for controlling output of a driving power source or motor installed in a vehicle, the relationship between a primary output-controller, which is manipulated by the user, and a secondary output-controller, which directly operates the motor, is regulated by control parameter subjected to evolution by using evolutionary computing based on at least one of the following: the user's characteristics, driving conditions, environmental changes, and deterioration of the drive power source with time. The evolution is conducted on-line or on a real-time basis. The primary output-controller includes an acceleration pedal or grip, and the secondary output-controller includes a throttle valve for an internal combustion engine or a running current controller for an electric motor.

Abstract: A data estimation capability using a FNN to estimate engine state data for an engine control system is described. The data estimation capability provides for making data relating to the engine state available as control parameters in a simple, inexpensive manner. The data estimation includes using data from one or more sensors as inputs to a FNN to estimate unmeasured engine operating states. The data estimates are provided as control parameters to an engine control system. The FNN can be used to provide data estimates for engine state values (e.g. the exhaust air fuel ratio, the exhaust NOx. value, the combustion chamber temperature, etc.) that are too difficult or too expensive to measure directly. Each FNN can be configured using a genetic optimizer to select the input data used by the FNN and the coupling weights in the FNN.

Abstract: Optimization of a FNN (FNN)-based controller is described. The optimization includes selecting which input signals will be used by the FNN to compute a desired control output. Output parameters are identified and computed by fuzzy reasoning using a neural network. Adjustment of fuzzy rules and/or membership functions for the FNN is provided by a learning process. The learning process includes selecting candidate input data signals (e.g. selecting candidate sensor signals) as inputs for the FNN. The input data is categorized and coded into a chromosome structure for use by a genetic algorithm. The genetic algorithm is used to select an optimum chromosome (individual). The optimum chromosome specifies the number(s) and type(s) of input data signals for the FNN so as to optimize the operation of the FNN-based control system. The optimized FNN-based control system can be used in many control environments, including control of an internal combustion engine.

Abstract: A reduced control system suitable for control of an engine as a nonlinear plant is described. The reduced control system is configured to use a reduced sensor set for controlling the plant without significant loss of control quality (accuracy) as compared to an optimal control system with an optimum sensor set. The control system calculates the information content provided by the reduced sensor set as compared to the information content provided by the optimum set. The control system also calculates the difference between the entropy production rate of the plant and the entropy production rate of the controller. A genetic optimizer is used to tune a fuzzy neural network in the reduced controller. A fitness function for the genetic optimizer provides optimum control accuracy in the reduced control system by minimizing the difference in entropy production while maximizing the sensor information content.

Abstract: An autonomic system for updating a fuzzy neural network includes a process of calculating an estimated value based on fuzzy inference by using a neural network structure, wherein a parameter to be adjusted or identified by fuzzy inference and outputted from the neural network is made to correspond to coupling loads which are updated by learning, i.e., fuzzy rules and membership functions are adjusted by learning. This system is characterized in that the addition and deletion of fuzzy rules are conducted based on changes in output errors in an autonomic manner, thereby effectively obtaining appropriate numbers of fuzzy rules optimal for an object such as a vehicle engine having strong non-linearity. Fuzzy rules are formed by a combination of membership functions representing variables such as an engine speed and a throttle angle.
