摘要:
In this paper, an energy efficiency improvement strategy is developed using a simplified current sensorless dynamic direct voltage maximum torque per ampere (MTPA) speed control method of interior permanent magnet synchronous motors (IPMSMs) for electric vehicle applications. Tracking the MTPA angle using a unique voltage amplitude without current sensing at any electric vehicle's speed yields minimum current/power consumption and high energy efficiency. These aims are achieved by considering the dynamic model of the motor that improves the controller reaction and accuracy during the transient states as contrary to the existing literature. Moreover, the simplified current sensorless dynamic direct voltage control (DDVC) technology contains a couple of control gains versus three times that with the classical MTPA Field-oriented control (FOC) method. Moreover, a comparative validation of the simplified current sensorless dynamic direct voltage MTPA methodology and the FOC strategy is executed. Experimental results with energy consumption measurements and energy efficiency study prove that the proposed simplified DDVC MTPA strategy is a promising alternative to the existing MTPA technologies of IPMSMs' drives as it preserves high energy efficiency during transient.
