Question

A worker is residing inside an air-conditioned cabin in an industrial environment. Temperature regulating section of the cabin is shown in the figure. Gc is the steady-state gain of the heating/cooling device (controller) built into the cabin, while Gp represents the steady-state gain associated with the thermal characteristics of the worker. H is the gain with which the internal temperature is fed back to the controller. The operating internal temperature (y) of the cabin is allowed to be 30°C at maximum while external temperature can go up to {a}°C. The required condition is achieved with Gc= 3 Gp=2, and H= .....Note:Here, “a”is a variable and the result shouldbein terms of “a”.
