The introduction of the differential action is helpful to reduce overshoot, overcome oscillation and indirectly enable a temperature control system to tend to be stable, and the action of a differential link is determined by a differential time constant TD. The greater the TD, the greater its effect of suppressing the variation in the deviation e (t); the smaller the TD, the weaker it will have against the change in deviation e (t).
