You can choose to do either one of the following two subproblems. (1) For the circuit system below, derive the state space model. Note that the input u is a current, the output y is a voltage, and one of the resistors has a negative resistance -1 ohm. u = iin u(t) b 1F HE 711 w -152 ΙΩΣ (2) For the mass-damper system below, the input u(t) is a velocity, the three mass elements have the same mass m and velocities V₁, V2, U3, respectively, the each of the four dampers has damping coefficient b. Suppose the output of the system is the net force F₂(t) acting on the middle mass element in the rightward direction. Derive the state space model of the system.
