摘要:
A sequence controller, employing digital techniques, employs clock pulses to energize and deenergize incremental loads sequentially at spaced intervals to correct the deviation of a sensed condition from a setpoint. The clock is inhibited from producing pulses when no deviation requiring correction exists. A feedback provides anticipation for the effect of the energization and deenergization of condition changing loads. Hunting is substantially eliminated.
