Consider a unit feedback control system with open-loop transfer function G (s) = K/ [s (s + 1)]. The steady state error of the system due to a unit step input is
Bode plot of a stable system is shown in figure below. The transfer function of the system is
Given: KK1 = 99; s = j1 rad/s, the sensitivity of the closed-loop system (shown in the figure) to variation in parameter K is approximately
The state representation of a second order system is x1 = x1 u, x2 = x1 2x2 + u Consider the following statements regarding the above system: 1. The system is completely state controllable. 2. If x1 is the output, then the system is completely output controllable. 3. If x2 is the output, then the system is completely output controllable. Of these statements
The number of roots of s3 + 5 s2 + 7 s + 3 = 0 in the left half of the s-plane is
The maximum phase shift that can be provided by a lead compensator with transfer function <table><tr><td rowspan="2">Gc(s) = </td><td style="border-bottom:1px solid #000000;vertical-align:bottom;padding-bottom:2px;"><center>1 + 6s</center></td></tr><tr><td style="text-align: center;">1 + 2s</td></tr></table> is
An integral controller is used to improve the transient response of a first order system. If G (s) = 1/1 + s and the system is operated in closed-loop with unity feedback, what is the value of Ti if integral controller transfer function is 1/Ti s to provide damping ratio of 0.5?
The open loop transfer function of a unity feedback control system is given by: <table><tr><td rowspan="2">G(s) = </td><td style="border-bottom:1px solid #000000;vertical-align:bottom;padding-bottom:2px;"><center>K</center></td></tr><tr><td style="text-align: center;">s(s + 1)</td></tr></table> If the gain K is increased to infinity, then the damping ratio will tend to become
A process with open-loop model <table><tr><td rowspan="2">G(s) =</td><td style="border-bottom:1px solid #000000;vertical-align:bottom;padding-bottom:2px;"><center>Ke sT4</center></td></tr><tr><td style="text-align: center;"> s + 1</td></tr></table> is controlled by a PID controller. For this process
