1 2. A system has open loop transfer function G(s) s(s? + s+ 1)(s +2) (a) the open loop system. Using the Routh Hurwitz test (or otherwise) discuss the pole locations for (b) also includes a proportional controller having gain K, as shown in figure 2. What is the closed loop transfer funtion for the system? The system is then enclosed in a unity gain, negative feedback loop that R(s)- K G(s) -Y(s)

For the circuit in Figure 2, consider that switch 1 has been open for a long time and at t=0 it closes, at the same time time (t=0) switch 2 opens. Taking into account the above, it is requested: to. Simulate voltage in the capacitor and current in the coil for times t<0 when it is in steady state. b. Simulate voltage and current for times t>0 until it reaches steady state (speed permanent). Also, get the initial voltage of the coil and the initial current of the capacitor just right after the change. c. Obtain the equations of voltage and current in the coil and then make graphs for each of them. these variables.
