Under the three-phase unbalanced grid condition, the commonly used controller design methods of three-phase voltage source rectifiers (VSR) are based on the instantaneous power model and the current and voltage double-closed loop control structure. The inner current loop proportional integral (PI) controllers are designed for the positive- and negative-sequence current components, separately, therefore,...
Model predictive control (MPC) strategy is a typical optimization predictive control method. MPC can achieve satisfying control performance with lower model parameter dependency, and it has been widely applied in process control systems. To improve the system reliability and reduce the hardware cost, extended Kalman filter (EKF) was introduced to achieve sensorless operation. A novel speed sensorless...
We present a simplified Mixed Logical Dynamic (MLD) model for DC-DC Boost converter using less number of binary variables and continuous variables. A constrained optimal problem is formulated and solved based on Model Predictive Control (MPC) using the simplified MLD model. The optimized switching signal derived by the MPC regulates the output voltage. The MLD modeling of the converter is accurate...
