Voltage Utilization Enhancement of Dual Inverters by Model Predictive Control for Motor Drive Applications

Abstract

This paper proposes a model predictive control (MPC) method to improve the voltage utilization of dual inverters compared to utilizing previously addressed techniques. The enhancement can reach up to 10% and this benefit has been through simulations on an open-end winding induction motor. I.

Design and Implementation of Model Predictive Control Based PID Controller for Industrial Applications

“…Consequently, most advanced control theory is performed in a hierarchical control structure in various applications, for example, power system [23] and robotics [24]. MPC is an APC algorithm that has significant advantages, particularly for the MIMO system with constraints [25][26][27][28]. Regardless of the MPC effectiveness, it is still applied at the supervisory level for most industrial applications in optimizing the set point of the process instead of regulating the control loop due to human constraints and computational burden [29][30][31].…”

Technical Review of Dual Inverter Topologies for More Electric Aircraft Applications

“…It is reported the dual inverters can enhance their performance by identifying appropriate voltage ratios. The improvement consists of improving the converter output quality by increasing the number of output voltage levels [25], [31], [33]- [38] and boosting the DC-link voltage utilization [16], [25], [39]- [42]. However, similar to a CHI, an FCI, or a DCI, the capacitors' voltages of the dual inverters also have to be properly controlled.…”
