Five Level Diode Clamped Converter
Since the topology of the diode-clamped converter (DCC), also known as neutral-point-clamped converter, was proposed in the early 80’s by Nabae et al. [1981], multilevel power converters are being increasingly employed in the industry, mainly in high-power applications.
Bidirectional power flow, near sinusoidal currents and high efficiency are some of the attractive features that these power conversion systems present.

Furuta Pendulum
The Furuta pendulum, or rotational inverted pendulum, consists of a driven arm which rotates in the horizontal plane and a pendulum attached to that arm which is free to rotate in the vertical plane. It was invented in 1992 at Tokyo Institute of Technology by Katsuhisa Furuta and his colleagues. It is an example of a complex nonlinear oscillator of interest in control system theory. The pendulum is underactuated and extremely non-linear due to the gravitational forces and the coupling arising from the Coriolis and centripetal forces.

Self-balanced systems are undergoing a considerable development nowadays. They have been made popular by the vehicle called Segway. Its control around the vertical position can be studied by applying linear methods and does not present special problems. However, when problems associated to the increase of the domain of attraction are to be tackle, the use of nonlinear methods become inevitable and the problem gains a remarkable difficulty.
