Design a Lead-Lag compensator for the system G s1 s s4 s10 To meet the following specifications Steady state error to a step input is 0 Steady state error to a ramp input is less than 01 Phase margin 25 deg - 0125. First of all we need to find the closed loop bandwidth to meet the transient response requirement OS20 Ts 02s.
A Draw the Bode plot of the uncompensated system and calculate the phase and gain margins of the system. Desired dominant closed-loop poles. Design a lead compensator so that the closed loop system meets the following specifications i Velocity error constant is greater than 10s.
Sketch the root locus of the system whose open loop transfer function is G S K S S2 S4. The gain crossover frequency is at least 12 rads. From the settling time spec we see that the real part of.
The steady-state error due to a unit-step disturbance input Ds is less that or equal to 5. Required for Root Locus The closed loop TF. Consider a system whose open loop transfer function is given by 13 1.
Answer to Solved Design a Lead-Lag compensator for the. OS20 Ts02s and Kv50. Electrical Engineering questions and answers.
3- We need to reshape the open loop transfer functions frequency response to meet. S K G s Design a passive lag-lead compensator using Bode diagrams to yield a 1325 overshoot a peak time of 2 seconds and Kv12. Meet the given specification.
- steady state error to a unity rate ramp is equal or less than 005 and - the damping ratio is equal or greater than 07. G_cs frac-6662s045s15. OS 20 Ts02 K v 50 2 Solution 1.
Sketch the root locus of the lead compensated system. 2- Bandwidth is related to both ƺ damping ratioand Ts settling time or Tppeak time. And Gain Margin 10dB.
Ii Mp 2. The gain crossover frequency is between 4 and 10 rads. Design a Lead compensator to place the dominant poles at the desired places while neglecting the effects of the Lag compensator.
Draw the Bode plot and find K for the following two cases. Find that value of K proportional controller. Design a lag or lead compensator Cs such that the following specifications are met.
This circuit has a transfer function of R 2 R 11 R 1 C 1 s1 R 2 C 2 s and thus provides one pole and one zero which can be placed anywhere on the negative real axisWhen the zero is closer to the origin than the pole this circuit is referred to as a lead compensator and. Desired system is K. I came up with the following compensator which gives the required specifications.
1- Phase margin is related to OS. You are required to design a lead compensator Gcs to meet the following specifications. Lead Compensation Techniques Based on the Root-Locus Approach.
AThe settling time is t s 5 sec bThe step response overshoot M p 163 cThe steady state error to a unit ramp is 10. ωωn2 rads Performance specification Damping ratio Damping ratio ζζ05 Undamped natural freq. Ηere is an open-loop transfer function and specifications for compensator design.
Due to its simplicity and And secondly by drawing root-locus plot of the uncompensated effectiveness phase lag and lead compensation is essential for system ascertain whether or not the gain adjustment alone can various frequency-based design methods especially for design yield the desired closed loop poles. The steady-state error due to a unit step disturbance is no more than 1. I defined the required poles and defined the angles according to the normal procedure of the root locus method and determined the zero and pole of the lead compensator.
What is your angle of deficiency. There is a proportional controller which will meet the transient specifications. S Compensator Controller.
Then design the Lag compensator to meet the SSE specifications. The open loop transfer function of a unity feedback control. I Gain margin equal to 6db ii Phase margin equal to 45.
