This thesis focuses on implementation of the swing-up, switching and stabilizing controllers for the rotary inverted pendulum. An energy based method to swing-up the pendulum and a state feedback controller to keep the pendulum in the upright position are employed. The mixed H2/H∞; state feedback controller is used to stabilize the pendulum with reduced oscillations. The results have been compared with the standard full state feedback and LQR. The Quanser rotary inverted pendulum is used as the testbed. All controllers are implemented in real-time using dSPACE 1104 rapid prototyping system. Microstick II with dsPIC33FJ128MC802 and Simulink embedded target for Microchip® is used as a standalone way to implement the controllers.

The diploma thesis deals with control of rotary inverted pendulum - Furuta pendulum. Solution for power electronics, sensors and coupling with PC is described, identification of parameters and nonlinear simulation model in Matlab/Simulink and SimMechanics toolbox is presented. Second type Lagrange equation is used for determination of equations of motion. Controll system based on state-space model of mechanism and LQR algorithm for design of state-space controller is used and switching between swing-up cotroller a stabilizing state-space control is achieved according to actual angular position of pendulum's angle. Input integrator eliminating steady state error was used with success.

Aim of this thesis is building of a simulator model of a rotary (Furuta) pendulum and design of appropriate regulators. This paper describes assembly of a nonlinear simulator model, using Matlab–Simulink and its library Simscape–Simmechanics. Furthermore the paper discuss linear discrete model obtained from the system response, using least squares method. This linear model serves as aproximation of the system for designing of two linear discrete state space regulators with sumator. These regulators are supported by a simple swing–up regulator and logics managing cooperation.
