Eliminate the noise in real time motor response graph

Hi all, Currently I am working on a Robocar modeling project. I will obtain a motor response as a result from the real-time simulation. There are noise generated by the Robocar itself during the simulation, which it directly affect the performance of the systems.

My question is how to implement a 1st or 2nd filter to eliminate the noise in the motor response graph? Thanks you.

In MATLAB or in Simulink?

Do you have the filter toolbox?

[Shawn Chang]

In Matlab GUI, the motor response graph is plot in GUI through axes. In simulink there are filter toolbox.

Is the filtering to be done at the MATLAB level or at the Simulink level?

[Shawn Chang]

if possible, it need to be done in MATLAB level. this motor response graph is show at the link below and the noise indicated are the one need to be filter out.
