A control system with a PD controller is shown in the figure. If the velocity error constant $${K_v} = 1000$$ and the damping ratio $$\zeta = 0.5,$$ then the values of $${K_P}$$ and $${K_D}$$ are GATE ECE 2007 Control Systems - Compensators Question 10 English

GATE ECE 2007 Control Systems - Compensators Question 10 English

$${K_P} = 100,{K_D} = 0.09$$

$${K_P} = 100,{K_D} = 0.9$$

$${K_P} = 10,{K_D} = 0.09$$

$${K_P} = 10,{K_D} = 0.9$$
