ABSTRACT
Mechatronics is a term of relatively recent origin and usually is defined as a combination of mechanics, electronics, and computer technology, often in the context of a feedback control system. Automotive engine control systems are a good example. Here a multitude of sensors measure various temperatures, pressures, flow rates, rotary speeds, and chemical composition and send this information to a microcomputer. The computer integrates all this data with preprogrammed engine models and control laws and sends commands to various valves, actuators, fuel injectors, and ignition systems so as to manage the engine's operation for an optimum combination of acceleration, fuel economy, and pollution emissions.
