Symmetrical Three-Vector-Based Model Predictive Control With Deadbeat Solution for IPMSM in Rotating Reference Frame

A Dual-Vector Modulated Model Predictive Control Method for Voltage Source Inverters with a New Duty Cycle Calculation Method

“…Additionally, compared to the conventional deadbeat control theory-based dual-vector MPC method [13][14][15][16][17][18][19][20][21], the proposed method in this paper can reduce the computational time, mainly because the duty cycle calculation method of this paper is simpler with reduced mathematical operation than that of the conventional dual-vector MPC method [13][14][15][16][17][18][19][20][21]. Thus, less digital processing time is required.…”

“…An MPC strategy was designed to control the current of two-level voltage source inverters in [6] in 2007. From then on, many researchers began to study new MPC strategies to reduce the computational time [7,8], to lower the switching frequency [9,10], to suppress the common-mode voltage [11,12], to decrease the current ripples [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], or to minimize the power ripples [30][31][32].…”

“…Additionally, as a flexible control method, MPC strategies are also studied in [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] to reduce the current ripples by using more voltage vectors instead of only one in every control cycle. In [13][14][15], dual-vector MPC strategies are studied.…”

“…Moreover, in [16][17][18][19][20][21], three voltage vectors are chosen per control cycle to further enhance the control performance, and better results are obtained. In these methods in [13][14][15][16][17][18][19][20][21], the duty cycles of each voltage vector are figured out according to the deadbeat control theory. Although duty cycles can be calculated accurately theoretically, the actual calculated duty cycle may be smaller than zero or larger than one, which reduces the control performance to a certain extent.…”

A Hybrid Predictive Control for a Current Source Converter in an Aircraft DC Microgrid

“…There are typically two kinds of predictive control schemes: deadbeat predictive control (DBPC) and finite-set model predictive control (FS-MPC). DBPC generates the reference signals based on the prediction models, and a linear modulation scheme is usually used in the inner loop to operate the converter [19,20]. On the contrary, FS-MPC relies on the minimization of the defined cost function to select the optimal switching state for the converter, and eliminates the modulator.…”
