345 +== **Model Tracking Control Function** ==
346 +
347 +Model tracking control is suitable for position control mode, which adds a model loop outside the three loop. In the model loop, new position commands, speed feedforward and torque feedforward and other control quantities are generated according to the user's response requirements to the system and the ideal motor control model. Applying these control quantities to the actual control loop can significantly improve the response performance and positioning performance of the position control, the design block diagram is as follows:
348 +
349 +(% style="text-align:center" %)
350 +[[image:20230515-7.png]]
351 +
352 +The usage method and conditions of model tracking control:
353 +
354 +~1. Correctly set the inertia ratio of the system P3-1, which can be obtained by monitoring the real-time load inertia ratio of U0-20.
355 +
356 +2. Set the load rigidity level P3-2, set an appropriate value, it is not need to set a high rigidity level (recommended value 17~~21 under rigid load).
357 +
358 +3. Set P2-20=1 to enable the function of model tracking control.
359 +
360 +4. Adjust the P2-21 model tracking control gain from small to large, and gradually increase in steps of 1000 until the responsiveness of the system meets the actual demand. The responsiveness of the system is mainly determined by this parameter.
361 +
362 +5. After the responsiveness meets the requirements, user can adjust the parameters appropriately to increase the load rigidity level P3-2.
363 +
364 +**✎Note**: Model tracking control is only available in position mode, and cannot be used in other modes.

433 +
434 +== **Gain switching** ==
435 +
436 +Gain switching function:
437 +
438 +●Switch to a lower gain in the motor stationary (servo enabled)state to suppress vibration;
439 +
440 +●Switch to a higher gain in the motor stationary state to shorten the positioning time;
441 +
442 +●Switch to a higher gain in the motor running state to get better command tracking performance;
443 +
444 +●Switch different gain settings by external signals depending on the load connected.

346 346  When the mechanical rigidity is low, vibration and noise may occur due to resonance caused by shaft twisting, and it may not be possible to increase the gain setting. In this case, by using a notch filter to reduce the gain at a specific frequency, after resonance is effectively suppressed, you can continue to increase the servo gain. There are 2 methods to suppress mechanical resonance.

802 +**Torque instruction filter**
349 349  
350 350  By setting the filter time constant, the torque instruction is attenuated in the high frequency range above the cutoff frequency, so as to achieve the expectation of suppressing mechanical resonance. The cut-off frequency of the torque instruction filter could be calculated by the following formula:

357 -The notch filter can achieve the expectation of suppressing mechanical resonance by reducing the gain at a specific frequency. When setting the notch filter correctly, the vibration can be effectively suppressed. You can try to increase the servo gain. The principle of the notch filter is shown in __[[Figure 7-3>>https://docs.we-con.com.cn/bin/download/Servo/2.%20User%20Manual/06%20VD2%20SA%20Series%20Servo%20Drives%20Manual%20%28Full%20V1.1%29/07%20Adjustments/WebHome/image-20220608174259-3.png?rev=1.1]]__.

361 361  The VD2 series servo drives have 2 sets of notch filters, each of which has 3 parameters, namely notch frequency, width grade and depth grade.
362 362  
363 -**(1) Width grade of notch filter**
817 +**Width grade of notch filter**
364 364  
365 365  The notch width grade is used to express the ratio of the notch width to the center frequency of the notch:

369 369  
370 370  In formula (7-1), [[image:image-20220706155946-7.png]] is the center frequency of notch filter, that is, the mechanical resonance frequency; [[image:image-20220706155952-8.png]] is the width of notch filter, which represents the frequency bandwidth with an amplitude attenuation rate of **-3dB** relative to the center frequency of notch filter.
371 371  
372 -**(2) Depth grade of notch filter**
826 +**Depth grade of notch filter**
373 373  
374 374  The depth grade of notch filter represents the ratio relationship between input and output at center frequency.
375 375  
376 -When the notch filter depth grade is 0, the input is completely suppressed at center frequency. When the notch filter depth grade is 100, the input is completely passable at center frequency. Therefore, the smaller the the notch filter depth grade is set, the deeper the the notch filter depth, and the stronger the suppression of mechanical resonance. But the system may be unstable, you should pay attention to it when using it. The specific relationship is shown in __[[Figure 7-4>>https://docs.we-con.com.cn/bin/download/Servo/2.%20User%20Manual/06%20VD2%20SA%20Series%20Servo%20Drives%20Manual%20%28Full%20V1.1%29/07%20Adjustments/WebHome/44.png?rev=1.1]]__.
