Digital deadbeat control method and experiment for non-minimum phase boost converterThis thesis discusses the proposal of nonlinear deadbeat control for continuous conduction mode (CCM) boost converter and the experimental veri cation. First, the nonlinear state equation is derived, and second a nonlinear current reference deadbeat control is proposed. Third, a new nonlinear controller to implement the load disturbance compensation is proposed. After the simulations using PSIM software and veri cations by experiments, it was con rmed that under the conditions of an input voltage 12 V, an output voltage of 20 V, a load resistance of 4 and a sampling frequency of 100 kHz, the voltage command tracking capability of a settling time of 280 s was achieved, and an output voltage recovery time of 1:46 ms was achieved for a sudden unknown load change. Mathematical analysis was performed and con rmed asymptotic stability and robustness of the control method during voltage and current perturbation, disturbance occurrence and parameter variations. It was con rmed that the voltage and cur- rent errors eigen values converge towards inside of the unit circle thus maintaining asymptotic stability for each perturbation case investigated. Methods to design the controller parameters were stipulated to be within the physical realization and can be applied to boost converter of any application in CCM. The proposed control method was compared with other literature that applied di erent digital control methods to boost converters of various applications. It was found that nonlinear deadbeat control proposed in this thesis was about twice as fast for reference tracking response, and could reject disturbances quickly for a load current three times bigger than other literature. Therefore, it is concluded that these data are the best even though the proposed control is based on nonlinear equations. Few di erences were observed between experiments and simulations. Upon investigations, those di erences were found to be caused by time delay in the switching device and other un-modeled nonlinear switching device phenomena. Future work will be focused on improving the control method to compensate for those observed nonlinearities.
