Paper Ideas to follow up

Current paper 2 plan (29 Oct 2022)

1. Show why 2D gain scheduling is required  +  2D gain scheduling considering speed and levitated height + LQR filter  for designing the PID controller in the gain scheduling + as you go lower, as you go closer to the bottom actuator, make the objective function take sign of the error into consideration, rather than simple xQx, quadratic under the effect of 1X disturbing force.

Notch filter based(29 Oct 2022)

1.  Instead of notching filter (Herzog 1996) + Tracking control for machining spindles, shift the notch filter central frequency around to balance between current consumption and vibration control. Also, based on the response to the 1X excitation force with the shifted notch filter, change the reference input adaptively: Called input trajectory optimization in https://ieeexplore.ieee.org/document/6859290, Nanu Chen

System identification + health monitoring (2 Nov 2022)

1. Do unbalance identification for health monitoring when the plant is originally controlled by LPV/gain scheduled control where RPM itself is a scheduling variable.

Active disturbance rejection control(29 Oct 2022)

ADRC is uses extended state observer ESO

ESO can be made time dependent, TADRC

Can you make ESO as parameter dependent (RPM ) dependent.

If ESO is itself state dependent (position) of plate, then does ESO become non linear. Can ADRC control it? "On disturbance rejection in magnetic levitation", Wei Wei, Wenchao Xue.

Algebraic successive integration scheme(29 Oct 2022)

1. FEM model with flexible rotor with algebraic successive integration for unabalance estimation and shaft model identification
2. Rigid rotor on AMB with algebraic successive integration for unbalance identification + km identification
3. Rigid rotor + AMB + algebraic successive integration for unbalance identification + Changing RPM + Notch filter tracking based on Herzog (03 Nov 2022)
4. Rigid rotor + AMB + algebraic successive integration for unbalance identification + Changing RPM + Notch filter tracking based on Herzog + With run out error on sensor disk (03 Nov 2022)
5. Impart thrust disk face out and thrust disk tilt on the 4 actuator supported thrust AMB, with rotation, in the first paper frame work on algebraic successive integration
