Design of electronic control unit for rotational inverted pendulum
Sopoušek, Radek ; Appel, Martin (referee) ; Brablc, Martin (advisor)
The scope of this thesis is to create a dynamic model of the pendulum, design the control in inverse position, implement the swing-up task and add a controlled fall to a stable position, design and integrate the hardware with the existing pendulum model and implement the control using a state machine. The reader is introduced to the elements of a real device. A model is analytically constructed to be used for parameter identification and control design. Swing-up control is implemented using the moment method and two energy methods representing single and multiple-swing behavior. In the inverse position, the pendulum is controlled using LQR controller. For controlled fall to stable position, PD controller is used. For control purposes, a developmental microprocessor board was selected and integrated into the existing model with minimal changes to the functionality. The control was performed using a state machine whose robustness to parameter changes was experimentally verified.
