Abstract
Deadbeat-direct torque and flux control has excellent dynamic-state and steady-state performance,but it is also sensitive to parameter variation.Parameter identification method integrated on DB-DTFC was dedicated.First, the parameter sensitivity of DB-DTFC was studied via theoretical analysis and simulation. Then,a model reference adaptive system parameter identifier was proposed to estimate magnetizing inductance and rotor time constant. Experimental results are in accordance with theoretical analysis,prove the validity of proposed method.关键词
