Made the theoretical state space model for us to compare with real

[luisdavidgarcia]

• Established the linear state space model with the matrices $A_c$, $B_c$, $C_c$, $D_c$ for the continuous-time system and $A_d$, $B_d$, $C_d$, $D_d$ for the discrete-time system.
• Included damping factor and small angle approximations: Small-angle approximation
