帮助里有详细的模块实现?: C- x; {1 _ G4 b* e
我看的该模块帮助写得很简略:
$ c4 z8 ~. `( f6 wThree-Phase PI-Controlled Phase Locked Loop
8 G3 ^9 o8 s' |& k+ ^) v% Y& k) X9 n& Q, O: Y) ~) y5 q
Description- S/ I/ L3 g, g. i, {6 c4 A
Input Parameters1 N4 O7 o- o% z+ {0 i( s( K
$ e6 s/ \0 f( n7 @" ?Description) n, l+ `. w% t3 e, y
This component is a 3-phase, PI controlled phase locked loop, which generates a ramp signal theta that varies between 0 and 360°, synchronized or locked in phase, to the input voltage Va. 3 J# L( B: `8 `$ ?
$ C6 m; s6 j. y
The Phase Vector Technique is used to generate the ramp. This technique exploits trigonometric multiplication identities to form an error signal that speeds up and slows down the phase-locked oscillator, to match the phase of the input. The phase error is passed as an output variable after conversion to degrees. The frequency of the input is computed and returned as an internal output parameter called Name for Tracked Frequency..

不知道你所说的帮助里有详细的模块实现是指的哪个帮助文件?
