Hybrid Optimal-Based Control of a Boost Converter

Recently, a new approach to control switching in a boost converter was developed based upon hybrid optimal control theory. A focus of the initial research was on the theoretical development of the control and using simulation to compare its performance to more traditional control approaches. Herein, the research is extended with a particular focus on the hardware implementation of the approach. Included in the implementation are techniques to compensate for delay resulting from computation and sampling. In addition, a new parameter estimator has been derived to estimate load resistance and source voltage required by the controller. The results of time-domain simulation and hardware experiments are used to validate the performance of the hybrid optimal control and estimator.
