Analog & Digital Control of an Electronic Throttle Valve

Abstract :-
Two electronic throttler controllers were designed and implemented for an automotive throttle valve on a four-cylinder, spark-ignition gasoline engine. The first controller was designed using operational amplifiers and other analog componentry to realize a proportional-integral controller and feedback loop. The second controller utilized a programmable digital microcontroller to replace the analog component for signal processing. Continue reading Analog & Digital Control of an Electronic Throttle Valve
