P70 关于锁相环自然频率的推导结果是错误的吧?Kp/Ki参数也是不对的,还在例程中使用。

min zhou2,
sprabt4a.pdf 推导的结果是准确的,SolarLib.pdf 手册将做出修改。
Using settling time of 30 ms, error band of 5% and damping ratio of 0.7, the natural frequency of 158.6859
can be obtained; and then back substituting you get Kp = 222.1603 and Ki = 25181.22.
is the correct values。
另外您可以看下C:\ti\controlSUITE\libs\app_libs\solar\v1.2 中的excel 表格: spll_coeff_compute.xlsx
再次感谢!
