What Is Control System. Many variables can be handled simultaneously. Steady state is function of time? Which of the following statements is correct for a system with gain margin close to unity or a phase margin close to zero.The derivative controller produces a control action based on the rate of change of error signal systsms it does not produce corrective measures for any constant error. Define Damping ratio. Answer : The Feedback in Control System in one in which the output is sampled and proportional signal is fed qusstions to the input for automatic correction of the error any change in desired output for futher processing to get back the desired output.
