CAR BRAKING SYSTEM MODELLING & CONTROL
Name:
Institutional Affiliation:
* Simulink model
Display1sGain K+_Input signal (ft)
* Response to step input.
Generally,
so
We now note several features about this equation, namely
Thus we can write the general form of the unit step response as:
 
* Limitations of K
K is subject to changes in the spring stiffness.
The friction also affects the value of K
QUESTION TWO
* The wheel is like a torus; a hollow cylinder
* Jw dwdt=FxRw-Tb Taking the right hand side, we know:
J w=Tb-Ta rolling resistance neglected
But Ta=FxRw and Fx=µFz
Combining these equations
Jw =Tb- FxRw
Differentiating with respect to t we get:
Jw dwdt=FxRw-Tb
C. We know that Fzf=m*gLr*+axhLr+Lf
And Fzr=m*gLf*+axhLr+Lf
