A Farm Equipment Manufacturer has a need to actively reduce the vibration of the operator's seat using an electrodynamic actuator. The frequency of operation varies from 1 to 10 Hz. Your goal is to develop the active control system of the seat. The seat without control (no actuators or sensors) will be referred to as Uncontrolled Seat.
1. Define the physical uncontrolled seat, including seat dimensions, weight, and springs and dampers characteristics.
2. Draw the block diagram of the uncontrolled seat.
3. Plot the open loop displacement response of the uncontrolled seat to a step input.
4. Plot the open loop displacement response of the uncontrolled seat to a random input with frequency between 1 to 100 Hz.
5. Plot the open loop velocity response of the uncontrolled seat to a step input.
6. Plot the open loop velocity response of the uncontrolled seat to a random input with frequency between 1 to 100 Hz.
7. Plot the open loop acceleration response of the uncontrolled seat to a step input.
8. Plot the open loop acceleration response of the uncontrolled seat to a random input with frequency between 1 to 100 Hz.
9. Define the parameters of the actuators and sensors.
10. Draw the open loop block diagram of the actively controlled seat when the controller Cs=1.
11. Plot the open loop displacement response of the controlled Cs=1 seat to a step input.
12. Plot the open loop displacement response of the controlled Cs=1 seat to a random input with frequency between 1 to 100 Hz.
13. Plot the open loop velocity response of the controlled Cs=1 seat to a step input.
14. Plot the open loop velocity response of the controlled Cs=1 seat to a random input with frequency between 1 to 100 Hz.
15. Plot the open loop acceleration response of the controlled Cs=1 seat to a step input.
16. Plot the open loop acceleration response of the controlled Cs=1 seat to a random input with frequency between 1 to 100 Hz.
17. Draw the closed loop block diagram of the actively controlled seat when the controller Cs=1.
18. Plot the closed loop displacement response of the controlled Cs=1 seat to a step input.
19. Plot the closed loop displacement response of the controlled Cs=1 seat to a random input with frequency between 1 to 100 Hz.
20. Plot the open closed velocity response of the controlled Cs=1 seat to a step input.
21. Plot the closed loop velocity response of the controlled Cs=1 seat to a random input with frequency between 1 to 100 Hz
22. Plot the closed loop acceleration response of the controlled Cs=1 seat to a step input
23. Plot the closed loop acceleration response of the controlled seat Cs=1 to a random input with frequency between 1 to 100 Hz.
