BAJA ATV longitudinal close loop model

Hello everyone,

I was modelling a longitudinal vehicle model for BAJA ATV. The model works somewhat correctly if its an open loop model i.e. giving signal manually and then getting the result. But when I try to model it as a close loop by giving the cvt ratio in the form of look up table I get the following warning 'Discontinuities detected within algebraic loop(s), may have trouble solving' and 'Input value of block 'BAJA_2021_WITHOUT_DISC/1-D Lookup Table' exceeds range of breakpoint vector for dimension 1.'. I have searched the error and got some soln like adding a saturation block and lowpass signal filter. these blocks helps upto a certain time then again give these types of warning.

1.) max velocity(m/s) above 4 is with saturaion block.

2.) max velocity(m/s) 1.4 is without saturaion block.

I have fired brakes at 35th sec and throttle is 1 throughout.

Also I dont know whats the matter with initial velocity in generic engine block like how that works and its value is affecting my o/p but dont know how.

It would be great if someone could help me out here.

engine data is baja standard data

cvt ratio is 3.9 to 0.5

Thank you.
