Introduction: The Heart of Modern Motion

% Sweep speed from 0 to 2x base speed sim('IPMSM_FluxWeakening.slx'); % Plot voltage magnitude figure; plot(tout, sqrt(vd.^2 + vq.^2)); ylim([0 350]); % See the voltage clamp at 173V (300/sqrt(3)) Implement a Current Reference Generator (CRG) using a lookup table that maps ( T_e^* ) and ( \omega_m ) to ( i_d^ , i_q^ ). Derive this table from the motor's voltage and current limits (the "MTPV" curve). Simulink's Optimization Toolbox can solve for this curve automatically using fmincon . Part 6: Debugging the "Simulation Doesn't Match Reality" You built the model. It works perfectly. The hardware fails. Why? Introduction: The Heart of Modern Motion % Sweep

Build the plant (motor + inverter) and the controller (FOC + SMO). Use variable-step solver ( ode45 or ode23t ). Verify torque tracking. Part 6: Debugging the "Simulation Doesn't Match Reality"
