Question 44984

Verified

Control System

a) Knowing the format of state space representation:

\dot{x}=A x+B u

y=C x+D u

If a second order system is modeled in a state space representation, what will be the dimensions of Aand B matrix?

b) Consider a system modeled via the third order differential equation:

\dddot{x}+3 \ddot{x}+4 \dot{x}+x=5 \dot{u}+u

Where, x(t) is displacement, u(t) is force. Develop a state space representation for the system. The desired output is all state variables.
