A steam turbine drives a compressor whose load can change with time.

A steam turbine drives a compressor whose load can change with time. Small variations in the shaft speed of the turbine are controlled through the use of fybal speed govemor. For this system shown in fig 1 below Speed Turbine Gas in governor compressor Gas out Steam Figure 1.0 steam turtbine and compressor a) identty al control objectives. b) kdertity all the avalable manipulated variables. ) Determine the basic control objective and suggest (sketch) a feedback control configuration that can be used to satisfy the control objective. d) Draw a closed loop block diagram for this control system.
