BIEEE-002 DIGITAL CONTROL SYSTEM
Time hours Maximum Marks: 70
Note: Attempt any seven questions. All questions carry equal marks. Use of scientific calculator is allowed.
1. Describe the important advantages offered by the use of digital computers as compensator devices in a control system. 5
What are the main problems associated with implementation of digital control? 5
2. State and prove the final value theorem of Z-transform. What is the condition under which the theorem is valid? 10
3. Consider the sample-data system of Figure 1. Determine its characteristic equation in and ascertain its stability using bilinear transformation. 10 <img src='./qimages/11235-3.jpg'> <br>
4. Define the regions of stability, marginal stability, and instability on the s-plane. How are these regions translated to z-plane by the mapping: z 10
5. A Linear Time Invariant system is characterized by the following homogeneous state equation:
x1 0 1 x1
=
x2 0 -2 x2
Compute the solution of the given equation assuming the intial state vector it 1
0
6. The motion of satellite in the equatorial plane is given by the following state equation: <img src='./qimages/11235-6.jpg'>
where,
w angular frequency deviations in position variables and respectively
x2(t), deviations in velocity variables and
u1(t) and the thrustsur and u8 thrusts in radial and
tangential directions
Assuming the tangential thruster becomes inoperable, determine the controllability of the system with the radial thruster alone. 10
7. Show that a BIBO stable continuous-time linear time invariant system is asymptotically stable only if the system is completely controllable and completely observable. 10
8. Briefly describe the configuration of a sampled-data system employing state feedback. Modify this configuration by introducing 'Integral state' to improve steady-state performance.
9. Write short notes on any two of the following: 5 5=10 Discrete Euler-Lagrange Equation for Optimal Digital Control Systems Stability Analysis using Lyapunov's method Digital Compensators
