ABSTRACT:
A servo control system and method for controlling repetitious or oscillatory motion of a member in a glass manufacturing process between predetermined points. A desired trajectory between such points is first established as a function of time, and this trajectory is then loaded into a digital electronic memory as a plurality of discrete trajectory position signals arranged in an incremental series as a function of time. Control logic, which includes a real time oscillator, periodically accesses the memory so as to sequentially select and read therefrom the incremental trajectory position signals. These incremental signals are fed as a desired position control signal to a servo amplifier, which receives a second input from a position transducer coupled to the movable member and provides an amplifier output to a servo motor and then to the member.
