Hello All!
This is my project:
Picture 1 is start of acim(Siemens P=90 kWt)
I use lib from TI.
And my problem an how to win it:
On low speed Use speed calculate freq speed(qep_posspeed_g.Speed_fr).On high speed region use period caclcalate speed(qep_posspeed_g.Speed_pr).
Please use field weaking pid to protect error ACIM and invertor.
Please use dead time correction to protect waveform sin and stability pid Iq and Id.
Picture 2 is reverse speed of ACIM.
On this picture you can see reverse speed of acim.
A use there not const Id and working in two region(torgue const. region and power const region).
I am glad to answere on you question.
Best reagard,Dmitry.
