Three tuning Omron s series controllers attempt to algorithms are used to recalculate the optimize the PID constants by using a Deviation PID constants within 500 ms after the Process limit cycle auto-tune. Although effective in immediately process value stabilizes at set point: after set Step-response most applications, this method has some point drawbacks. For example, the auto-tuning Step-response method must induce an upset into the process in Disturbance tuning order to make the process oscillate four Hunting tuning. Manipulated PID times. In many processes these types of artificial upsets are not desirable. Step-Response Method Adaptive tuning controllers do not induce Disturbance Tuning This tuning method takes place on start- an upset instead, they use information up and after an upward set point change from the actual process, eliminating heating applications or a downward set unnecessary oscillations and enabling Stable point change in a cooling application. quicker start-up time. SP range Step-response tuning changes mainly impact the proportional band. Another drawback of the limit cycle auto- Outside stable Disturbance tuning tune method is that PID constants will range here takes place here Disturbance Tuning only be effective so long as the same This tuning method takes place when the basic conditions that were present when temperature exceeds the stable range the auto-tune took place remain constant. between one and three times before Various factors such as a load change, Hunting Tuning settling back to set point.
