In order to suppress harmonics and optimize power grid quality for the indirect matrix converter (IMC), harmonic characteristics of the input current in IMC are analyzed. The classic dual space vector modulation (SVM) method is adopted for IMC. Generally, only the rough results of harmonic analysis can be achieved by using the conventional mathematical model based on the transfer function. In this...
In order to simplify the commutation in the virtual rectifier, a zero current commutation model predictive control (ZCC-MPC) method is proposed for the induction motor drive system fed by indirect matrix converter (IMC). Switching states combination is adopted in the virtual inverter instead of single predictive switching state, which ensures that the inverter stage keeps at zero voltage vectors during...
In order to characterize tension and establish control strategy of web press, a precise dynamical model of winding tension is established by analyzing a shaftless multiple unit web press experiment platform. Several simulation models are developed based on MATLAB which are winding tension module, diameter real-time calculation module, taper tension reference value module and servo motor module. A...
Indirect matrix converter (IMC) fed interior permanent magnet synchronous motor (IPMSM) drive is a novel solution for AC adjustable-speed drives with high performance and high efficiency. Position sensorless vector control technique is applied for the IMC fed IPMSM drive. Model reference adaptive system (MRAS) based rotor position estimation method is employed to estimate rotor position and speed...
