| Description | Journal: Iop Conference Series: Materials Science and Engineering This work proposes to develop mathematical model and event trigger control using a state observer, which precisely tracks position of the solid steel ball of magnetically actuated levitation system. The lumped uncertainties i.e. non-linarites exists in the magnetic levitation system, overwhelmed by the state observer. State space model was derived by the system equation. Based on desired specification required poles are placed using pole placement method to stabilize the closed loop system in response to a small size step input then full order observer estimate the state variables. Here ball position and coil current is directly measurable, but velocity is not directly measurable, which has been investigated in this work. |
