凸极电机弱磁控制仿真
我自己搭建的凸极永磁同步电机外部电压环弱磁控制模型图 外环的PI参数非常脆弱电机参数:3对极
定子电阻:0.217
磁链:0.158
直轴电感:0.398mH
交轴电感:0.894mH
转动惯量:0.065832
直流母线电压:384
额定转速:3600rpm
额定电压:220V
额定电流:124A
定子电流:300A
我的疑问:MTPA模块我的搭建正确吗
由于ψf/Ld=396>300A
电压外环的直轴电流我限幅是
那么id iq给定的限幅是怎样的,
电压外环的PI调节,参数只有那几个 换一下就容易出错误
希望大牛给予指导 望很快回复
模型忘记附上啦 补上来 xianyangfzt 发表于 2013-12-22 22:28
下载研究研究,希望可以共同讨论
有什么好的意见没 请问楼主是否调试好了弱磁的仿真 可否指导下 加入过调制后,可以把系数K提高,理论最大值1.1 楼主,没有相关参考论文吗?reference 也是相当重要啊 楼主,我运行后出现了错误,麻烦问一下这是怎么个情况
An error occurred while running the simulation and the simulation was terminated
Caused by:
Simulink cannot solve the algebraic loop containing 'MTPAC/Fcn1' at time 0.12355000000000001 using the TrustRegion-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues.
To rule out solver convergence as the cause of this error, either
a) switch to LineSearch-based algorithm using
set_param('MTPAC','AlgebraicLoopSolver','LineSearch')
b) reducing the ode23tb solver RelTol parameter so that the solver takes smaller time steps.
If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification. 您好 晚辈在学习弱磁相关知识刚好在论坛看到您的仿真 有一点想向您请教,就是 您的电机参数中的额定电压电流是怎么设置在电机模型中的呢我看simulink中PMSM电机模型中并没有额定电压电流选项 也很纳闷 想了很久您能解答我的疑惑吗 谢谢 1.电流环是否已经填好了呀?
2.电流环ok,弱磁环本身参数就应该偏小,你是不是给大了。 非常有用,感谢分享~~~~ MATLAB simulation
