Abstract: A simple, easy to implement adaptive control strategy for dc-dc converters based on a grid-point concept is presented in this paper. Multiple control laws are designed previously with respect to some defined operating points (grid-points). A parameter subspace associated with each grid-point can then be derived. The main idea is that the specified operation space is partitioned into small subspaces characterized by the grid-points, so that any disturbances can be localized to be small signals within a particular subspace. By switching the control law based on the associated grid-point best representing the actual operation, the operation range of the regulated converter is widened and the transient behavior is improved. Simulation results have shown its merit when large-signal disturbances are present in output load and input voltage.
