Zero-Crossing Detection Error...

Hello Every One...

Recently I faced an error which i couldn't get rid of...

it is about consecutive zero crossing... the error occurs even when i disabled

the un-ticked the 'Enable zero crossing detection' of PID Controller but it

didn't work.

The error dialog is:

"to continue the simulation, you may 1) Try using Adaptive zero-crossing

detection algorithm or 2) Disable the zero crossing of the blocks shown in the

following table.

---------------------------------------------------------

Number of consecutive zero-crossings : 1000

Zero-crossing signal name : RelopInput

Block type : RelationalOperator

Block path : 'boostwithpicontrol/Relational Operator1'

---------------------------------------------------------

You can turn off this message by using the MATLAB command:

set_param('boostwithpicontrol','MaxConsecutiveZCsMsg','none');

"

Would You Please Help...
