Description: 在分析无刷直流电机（BLDC）数学模型的基础上，提出了一种无刷直流电机控制系统仿
真建模的新方法。在Matlab/Simulink环境下，把独立的功能模块和S函数相结合，构建了无刷直流
电机系统的仿真模型。系统采用双闭环控制：速度环采用离散PID控制，根据滞环电流跟踪型PWM
逆变器原理实现电流控制。仿真和试验结果与理论分析一致，验证了该方法的合理性和有效性。
此方法也适用于验证其他控制算法的合理性，为实际电机控制系统的设计和调试提供了新的思路。
-Based on the mathematical model of the Brushless DC motor(BLDC),a novel method for modeling and
simulation of BLDC control system was proposed.In Matlab/Simulink,by the combination of the isolated functional blocks
and S-functions,the model of BLDC could be established.In the double loop of control system,a discrete PID controller was
adopted in the speed loop and a current controller was completed in the current loop on the principle of hysteresis current
track PWM inverter.The reasonability and validity were testified by the coincidence of the simulation and experimentation
results and theory analysis.This novel method is also suitable for verifying the reasonability of other control algorithms and
offers a new thinking for designing and debugging actual motors.

Description: 多相永磁同步电机驱动技术研究(博士论文)目前,三相电机驱动系统在电气驱动应用场合得到了广泛的应用,然而随着现代电力电子技术、计算机技术和控制理论的发展,由逆变器供电的电机驱动系统的相数不再受到供电相数的限制。特别在大功率、高可靠性和低直流电压供电应用场合,多相电机驱动系统比三相电机驱动系统更具优势,因此多相电机驱动系统特别适合于应用在舰船全电力推进、电动车辆、航空航天和军事等场合。其相关技术的研究为电气驱动技术的研究开辟了新的领域,多相电机驱动系统得到各国科研人员越来越多的关注和重视。 本文研究从任意相数多相电机出发,重点研究了五相永磁同步电机驱动系统,全文主要内容如下: 引入绕组函数理论定量分析了任意相数对称绕组的磁势时空谐波分布,说明了低次时空谐波在多相电机中的重要作用 首次从对称分量法推导出推广派克变换,并建立了n-m相感应电机数学模型,指出多相电机控制是一个多维控制问题。这些基础理论知识为分析多相电机奠定了理论基础。 建立了五相永磁同步电机派克方程,在此基础上研究了五相永磁同步电机中d-q子空间与广义零序子空间的耦合问题。并根据不同结构形式五相永磁同步电机的特点,详细讨论了不同情况下的多维矢量控制和解耦控制问题。

Description: In this paper a new approach to direct torque control
(DTC) of induction motor drive is presented. In comparison with
the conventional DTC methods [1], [22] the inverter switching frequency
is constant and is dramatically increased, requiring neither
any increase of the sampling frequency, nor any high frequency
dither signal. The well-developed space vector modulation technique
is applied to inverter control in the proposed DTC-based
induction motor drive system, thereby dramatically reducing the
torque ripple and speed ripple. Platform: |
