Resumo
In this work, a new real-time Simulation method is designed for nonlinear control
techniques applied to power converters. We propose two different implementations: in the first
one (Single Hardware in The Loop: SHIL), both model and control laws are inserted in the same
Digital Signal Processor (DSP), and in the second approach (Double Hardware in The Loop: DHIL),
the equations are loaded in different embedded systems. With this methodology, linear and nonlinear
control techniques can be designed and compared in a quick and cheap real-time realization of the
proposed systems, ideal for both students and engineers who are interested in learning and validating
converters performance. The methodology can be applied to buck, boost, buck-boost, flyback,
SEPIC and 3-phase AC-DC boost converters showing that the new and high performance embedded
systems can evaluate distinct nonlinear controllers. The approach is done using matlab-simulink
over commodity Texas Instruments Digital Signal Processors (TI-DSPs). The main purpose is to
demonstrate the feasibility of proposed real-time implementations without using expensive HIL
systems such as Opal-RT and Typhoon-HL.
