Dear Mathwork coomunity,
I have four 5D Look-Up tables with input and output parameters obtained with the following code using the attached simulation results file.
clc;
clear;
close all;
%read simulation data
Results = readmatrix('Stator_separeted.xlsx');
AngleR=Results(:,1);
AngleL=Results(:,2);
MMFL=Results(:,3);
MMFR=Results(:,4);
move=Results(:,5);
Torque=Results(:,6)*0.001;
Force=Results(:,7);
FluxL=Results(:,8);
FluxR=Results(:,9);
turns = 100; % number of turns;
% converting of simulation data
CurrentR = MMFR./turns;
CurrentL = MMFL./turns;
FluxLinkageL = FluxL*turns;
FluxLinkageR = FluxR*turns;
%axis vectors of 5D-Look-Up table (input simulation parameters)
AngleRvec = [-40;-35;-30;-25;-20;-15;-10;-5;0];
AngleLvec = [-40;-35;-30;-25;-20;-15;-10;-5;0];
CurrentLvec = [-700/turns; 0/turns; 700/turns; 1400/turns; 2100/turns];
CurrentRvec = [-700/turns; 0/turns; 700/turns; 1400/turns; 2100/turns];
movevec = [-4; -2; 0; 2; 4];
%reshape vectors of output simulation parameters to 5D-arrays
reshapeVec = [9 9 5 5 5];
FluxLinkageL = reshape(FluxLinkageL,reshapeVec);
FluxLinkageR = reshape(FluxLinkageR,reshapeVec);
Torque = reshape(Torque,reshapeVec);
Force = reshape(Force,reshapeVec);
My question is - how can these four 5D LUTs be inversed to the eight following 4D LUTs:
Inversion of Force-LUT Force(AngleR, AngleL, CurrentL, CurrentR, move) to CurrentL(AngleR, AngleL, Force,move) and CurrentR(AngleR, AngleL, Force,move);
Inversion of Torque-LUT: Torque(AngleR, AngleL, CurrentL, CurrentR, move) to CurrentL(AngleR, AngleL, Torque,move) and CurrentR(AngleR, AngleL, Torque,move);
Inversion of FluxLinkageL-LUT: FluxLinkageL(AngleR, AngleL, CurrentL, CurrentR, move) to CurrentL(AngleR, AngleL, FluxLinkageL,move) and CurrentR(AngleR, AngleL, FluxLinkageL,move);
Inversion of FluxLinkageR-LUT: FluxLinkageL(AngleR, AngleL, CurrentL, CurrentR, move) to CurrentL(AngleR, AngleL, FluxLinkageR,move) and CurrentR(AngleR, AngleL, FluxLinkageR,move).
Of course, if one of these LUTs can be inversed, the remaining can be inversed in the same way.
Please help me with this question.
