I am having problem in solving Simulink Model in MATLAB.
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/309617/image.jpeg)
I tried to solved this using following code
s=tf('s')
Phi=193.4/(s^2)
K_Phi=pid(0.3,0,0.2,100)
Phi_1=feedback(K_Phi*Phi,1,-1)
step(Phi_1)
I also tried on more method
K_Phi=pid(0.3,0,0.2,100)
Phi_1=feedback(Phi,1,-1)
Phi_2=Phi_1*K_Phi
step(Phi_2)
But, both ways aren't working kindly help me in solving this.

I think you should use lsim(...) because there’s a step input to the model.
