摘要:
用扩展的卡尔曼滤波算法(EKF)对表贴式交流永磁无刷同步电动机进行动态参数估计,根据电机控制系统中传感器检测到的电机定子电流、电压和转子的位置、转速等信号,推算电机定子绕组的电阻和转子的主磁通值,经过对电机模型和卡尔曼算法的分析,给出了电机控制系统的全阶卡尔曼滤波模型和经过简化处理后的降阶估计模型,用降阶的简化模型对系统进行估计后,得到了定子电阻和转子主磁通的结果,并分析了定子电阻和转子磁通估计值和实际值之间的误差,以及估计值随电机转速和负载大小变化的曲线.电机用脉宽调制(PWM)的电压源逆变器供电,用TMS320F2812系列数字信号处理器(DSP)作为控制芯片,用矢量控制的策略对电机进行转速控制.
Abstract:
The linear ized and reduced order Extended Ka lm an F ilter ( EKF) a rithm etic is em ployed in param eter identi fication inc lud ing estima te estim a tion o f the stator w ind ing resister and rotor flux linkag e in su rface-m ounted perm anent m agnet brush less AC m otor, according to stator vo ltages, cu rrents, rotor position and speed measured from the mo tor. H av ing ana lyzed them ode l o f themo tor and ar ithme tic of Ka lm an F ilter, we estab lish a full order and a reduced order o f Ka lm an Filterm ode,l and a lso obtain the estim ated va lue through the mode.l The error between rea l va lue and estima ted va lue is ana lyzed in the paper and the curves o f the resistance and flux-linkage, wh ich vary w ith speed, and the loads a re a lso ana lyzed in the paper. In them oto r control sy stem, PWM inverte r is used as powe r supp ly o f the m otor, and a new genera tion o f m icro DSP TM S320F281 is emp loyed as a controlle r. A t the end of the paper, the estima ted results o f sta to r resistor and rotor flux linkage are presented.
