As the motor and load are driven in the auto tuning process for this Yaskawa servo drive, the drive automatically determines the inertia of the system, measures oscillations, and sets, evaluates, and optimizes the control loop gains.Īdaptive tuning is similar to auto tuning, but goes one step further and allows for a wide range of parameters that will provide stable control of the servo system. In most cases, the auto tuning process can also add filters to the control loop to suppress oscillations caused by resonance frequencies in the system. That is, the performance of the motor is evaluated relative to a given command, and the servo drive automatically adjusts the gains until values are found that give the best performance.
AUTOMATIC CAR TUNING MANUAL
Although in the beginning, auto-tuning functions were useful only when the load was rigidly coupled and the system dynamics were relatively simple, more complex algorithms and faster computing power have enabled the development of auto tuning functions that are sophisticated enough to address even the most complex systems, with minimal input or effort from the user.Īuto tuning is based on the same principles as manual tuning. While manual tuning has been the predominant method for many years, most servo drives now incorporate functions that will automatically tune the system. In addition, tuning a servo drive usually requires adjustments to additional parameters including acceleration and velocity feed-forward gains and filters to reduce oscillations. It typically requires tuning multiple control loops, each with its own gains (proportional, integral, and/or derivative) to be adjusted. Tuning a servo system is a complex and iterative process.
