After building actuation system using Isothermal Liquid blocks (IL)(R2023a) in Simscape i got it connected to the MPC but it showing Plant model cannot be a pure direct feed-through system without additional dynamics but when i used the hydraulic blocks (R2020a) the plant got imported in mpc. Why the error coming while using IL block in simscape?

Hi Kiran,
I understand that you are looking to debug the following error:
Plant model cannot be a pure direct feed-through system without additional dynamics error.
Kindly provide the complete model & files associated with this error. MPC Controllers include a linearized plant model. If the model linearizes to "ss(0,0,0,0)", then the above error message will appear.
You can resolve the error by the following the below mentioned steps:
You may refer to the following MATLAB answer to know more about the error :
Hope this helps.
