auto-tuning

Definition

The appropriate product category Inverters: A function of an Inverter to automatically measure and record the circuit constants of a motor, including the constants of motor coil or amount of moment of inertia. There are two measuring methods: measurement using a rotating motor and using a motor that does not rotate. Auto-tuning is generally used for vector control.

The appropriate product category Controller NJ Series: The PID constant values and combinations that are used for temperature control depend on the characteristics of the controlled object. A variety of conventional methods that are used to obtain these PID constants have been suggested and implemented based on actual control temperature waveforms. Auto-tuning methods make it possible to obtain PID constants suitable to a variety of controlling objects. The most common types of auto-tuning are the step response, marginal sensitivity, and limit cycle methods.
