      Description

      Upgrade the rotator controller with new trajectory and deploy on summit.

      Based on Ander:

      If you compare our current “rotator_smlnk_Commands.xml” with the last develop commit, you could see that some elements have been removed because they were related to the previous control algorithm. Also, new parameters have been added for the new control:

      • Removed:
        MaxType1SlewPos
        MaxType2SlewPos
        pLoop_adaptationLimit
        pLoop_adaptaionGain
        pLoop_proportionalGain
        pLoop_integralGain
        pLoop_UserSpecVelocityCmdLimit
        vLoop_proportionalGain
        vLoop_integralGain
        vLoop_motorCurrentLimit
        sysBiasMod_forwardPlus
        sysBiasMod_forwardMinus
        sysBiasMod_reversePlus
        sysBiasMod_reverseMinus
        sysBiasMod_maxCurrent
        CoggingCompensationFlag
      • Added:
        PosLoop_Kv: Position loop’s controller proportional gain [rad/s]
        VelLoop_Kp: Speed loop’s controller proportional gain [rad/s]
        VelLoop_Ti: Speed loop’s controller integral time [s]
        CurrentLimit: Motor current limit [A]
        enableFFV: Logical value to enable or disable the controller’s speed feedforward term [0 = not active, 1 = active]
        Preload_Kp: Load sharing controller’s proportional gain [rad/s]
        Preload_Ti: Load sharing controller’s integral gain [s]
        Preload_Tq: Preload torque value [per unit, using maximum torque as 1]

      Note. The story point in this ticket contains the DM-34299.

            Collect the binary data from hardware:
            1. data_moog.log
            2. data_tekniker.log

            I did the calculation by myself in "Rotator Angle Calculation" and it looks like two models have similar results:

            Debugged the data and send to Ander for the further action.
