Chapter 6, Problem 48P
A linearized model of a torque-controlled crane hoisting a load with a fixed rope length is
P(s)=XT(s)FT(s)=1mTs2+ω20s2(s2+aω20)
where ω0=√gL , L = the rope length, mT= the mass of the car, a = the combined rope and car mass, fT= the force input applied to the car, and xT= the resulting rope displacement (Marttinen, 1990). If the system is controlled in a feedback configuration by placing it in a loop as shown in Figure P6.11, with K>0 , where will the closed-loop poles be located?

- Monthly exam 13 2021-2022 Power plant Time: 1.5 Hrs Q1. A The gas-turbine cycle shown in Fig. is used as an automotive engine. In the first turbine, the gas expands to pressure Ps, just low enough for this turbine to drive the compressor. The gas is then expanded through the second turbine connected to the drive wheels. The data for the engine are shown in the figure, and assume that all processes are ideal.
