The state vector 'x' in MMC is ordered as follows (from end to start): [iDelta_d, iDelta_q, iSigma_d, iSigma_q, iSigma_z, vCDelta_d, vCDelta_q, vCDelta_Zd, vCDelta_Zq, vCSigma_d, vCSigma_q, vCSigma_z] where:

• iDelta_d, iDelta_q : AC differential currents (d/q axis)
• iSigma_d, iSigma_q : Circulating currents (d/q axis)
• iSigma_z : Zero-sequence circulating current
• vCDelta_d, vCDelta_q : AC capacitor voltages (d/q axis)
• vCDelta_Zd, vCDelta_Zq : Zero-sequence capacitor voltages (d/q axis)
• vCSigma_d, vCSigma_q : Circulating capacitor voltages (d/q axis)
• vCSigma_z : Zero-sequence circulating capacitor voltage

Additional states (if present) are prepended for controllers, filters, PLL, and delay blocks. The index 'i' is set to (number_of_states - 12) to access the main MMC states above. Controller/filter/PLL/delay states are accessed at lower indices (i.e., x[0] ... x[i-1]).
