++== **Model Tracking Control Function** ==
++
++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:
++
++(% style="text-align:center" %)
++[[image:20230515-7.png]]
++
++The usage method and conditions of model tracking control:
++
++~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.
++
++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).
++
++3. Set P2-20=1 to enable the function of model tracking control.
++
++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.
++
++5. After the responsiveness meets the requirements, user can adjust the parameters appropriately to increase the load rigidity level P3-2.
++
++**✎Note**: Model tracking control is only available in position mode, and cannot be used in other modes.

++Please refer to the following for an example of the procedure of adjusting servo gain.
++
++|**Step**|**Content**
++|1|Please try to set the correct load inertia ratio parameter P3-1.
++|2|If the automatic adjustment mode is used (P3-3 is set to 0), please set the basic rigidity level parameter P3-2. If in manual adjustment mode (P3-3 is set to 1), please set the gain P2-1~~P2-3 related to the position loop and speed loop and the torque filter time constant P4-4. The setting principle is mainly no vibration and overshoot.
++|3|Turn on the model tracking function, set P2-20 to 1.
++|4|Increase the model tracking gain P2-21 within the range of no overshoot and vibration occur.
++|5|If the rigidity level of step 2 is set relatively low, user can properly increase the rigidity level P3-2.
++|6|When overshoot occurs, or the responses of forward rotation and reverse rotation are different, user can fine-tune through model tracking control forward bias P2-23, model tracking control reverse bias P2-24, model tracking control speed feedforward compensation P2 -25.

++== **Gain switching** ==
++
++Gain switching function:
++
++●Switch to a lower gain in the motor stationary (servo enabled)state to suppress vibration;
++
++●Switch to a higher gain in the motor stationary state to shorten the positioning time;
++
++●Switch to a higher gain in the motor running state to get better command tracking performance;
++
++●Switch different gain settings by external signals depending on the load connected.

  * Users can measure vibration by measuring equipment such as laser displacement．
  *  If no measuring equipment, the user can also read the position deviation waveform to confirm the vibration frequency through the "waveform" function of the PC debugging software.
  * Low-frequency vibration detection needs to be coordinated by the two parameters of completion positioning threshold and vibration detection amplitude. When the vibration amplitude is greater than (P5-12*P4-14 detection amplitude ratio), the low-frequency vibration frequency can be recognized and updated to U0-16 monitoring quantity. For example, when the vibration amplitude is greater than (P5-12*P4-14*0.001) detection amplitude ratio. For example, in P05-12=800, P04_14=50, the vibration amplitude is greater than P5-12*P4-14*0.001=800*50*0.001=40 pulses, stop vibration frequency can be identified in U0-16.

--**Vibration frequency detection:**
--
--The vibration frequency can directly obtain the value of the current vibration frequency from the software oscilloscope vibration frequency, combined with real-time speed waveform to observe the current vibration situation.
--
--**Debugging method:**
--
--* Please set the correct inertia ratio parameter P3-1 when using type A vibration suppression,
--* Run the position curve command, observe the servo host computer software waveform interface (sine wave) to obtain the vibration frequency.
--* Set P4-20 vibration frequency and enable type A vibration suppression function P4-19. ( Type A vibration frequency takes effect when P4-19 is set to 1 for the first time. If change A-type vibration frequency P4-20, please set P4-19 to 0 again, then set to 1)
--* Set P4-22 damping gain, gradually increasing from 0, each time increasing about 20.
--* Observe the size of the vibration speed component, if the amplitude speed component is getting larger, it can be the vibration frequency setting error, if the vibration speed component is getting smaller, it means the vibration is gradually suppressed.
--* When the vibration is suppressed, there is still a small part of the vibration speed component, users can fine-tune the P4-23 phase correction, the recommended value of 150~~300.

--|(% style="text-align:left; vertical-align:middle" %)Note: If there is a speed substantial vibration and the vibration increases during the debugging, it may be that the low-frequency vibration suppression is not suitable for the current working conditions, please immediately close the servo, or power down!
