Consider the following closed loop system with GₚandG_cas the transfer function of the process and the controller, respectively. For a unit step change in the set point(yₛₚ), the change in the value of the response ( y ) at steady state is ___(round off to 1 decimal place).

Options

none

Answer

1

Solution

..
..
..
Y=/frac/frac1s((0.1s+0.2)10)(0.5s(s+1)(2s+1)+(0.1s+0.2)10)Y = /frac{/frac{1}{s}((0.1s+0.2)10)}{(0.5s(s+1)(2s+1)+(0.1s+0.2)10)}
..
Y=1Y = 1
Hence, the correct answer is 1.
