Excellent control performance PID control algorithm and Z control algorithm are selectable according to the application. PID control algorithm: Conventional control method Z control algorithm: Our new algorithm (patent pending) which has evolved the PID control method. Especially, the effect can be expected such as overshoot suppression and speedy recovery in the event of disturbance control (during opening and closing of the electric furnace). |
