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.

Part 1:

1) Define the physical uncontrolled seat, including seat dimensions, weight, and springs and dampers characteristics.

2) Draw the block diagram of the controlled seat.

*Using MATLAB*

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 signal.

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 signal.

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 signal.

9) Define the parameters of the actuator and sensors.

10) Draw the open loop block diagram of the actively controlled seat when the controller C(s)=1

11) Plot the open loop displacement response of the controlled (C(s)=1) seat to a step input.

12) Plot the open loop displacement response of the controlled (C(s)=1) seat to a random input signal.

13) Plot the open loop velocity response of the controlled (C(s)=1) seat to a step input.

14) Plot the open loop velocity response of the controlled (C(s)=1) seat to a random input signal.

15) Plot the open loop acceleration response of the controlled (C(s)=1) seat to a step input.

16) Plot the open loop acceleration response of the controlled (C(s)=1) seat to a random input signal.

17) Draw the closed loop block diagram of the actively controlled seat when the controller C(s)=1

18) Plot the closed loop displacement response of the controlled (C(s)=1) seat to a step input.

19) Plot the closed loop displacement response of the controlled (C(s)=1) seat to a random input signal.

20) Plot the closed loop velocity response of the controlled (C(s)=1) seat to a step input.

21) Plot the closed loop velocity response of the controlled (C(s)=1) seat to a random input signal.

22) Plot the closed loop acceleration response of the controlled (C(s)=1) seat to a step input.

23) Plot the closed loop acceleration response of the controlled (C(s)=1) seat to a random input signal.
