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.
