Multiloop positioning control system

摘要: A servoamplifier forming part of a multiple feedback control system drives an electric motor to move machine programmed final position in response error signal. transducer connected sense the movement generates analog signal determined by distance between and reference point. data senses level enters digit into storage when moves unit distance. The compiles these entries produces digital absolute that indicates present machine. command generator, each such entry storage, electrically shifts point direction travel. comparator loop switch is greater than two units. When at predetermined level, connects coming from input drive its position.
