ABSTRACT:
According to a feedback control method, the response process of set point tracking control is divided into three, tracking, convergence, and stabilization phases. The phase is switched to the tracking phase at set point change start time as the tracking phase start time. The manipulated variable which causes the controlled variable to tracking the set point is continuously output in the tracking phase. The phase is switched to the convergence phase at, as the convergence phase start time, specific set point tracking control elapsed time at which the controlled variable does not exceed the set point in the tracking phase. A manipulated variable which converges the controlled variable to the vicinity of the set point is continuously output in the convergence phase. The phase is switched to the stabilization phase at, as the stabilization phase start time, time at which the controlled variable reaches a preset situation in the convergence phase. A manipulated variable which stabilizes the controlled variable at the set point is continuously output in the stabilization phase. A feedback control apparatus is also disclosed.
