Abstract:
Systems and methods for controlling a motion of an object from an initial location to a final location within a region while avoiding a set of obstacles located in the region. The systems and methods include selecting, the equilibrium points within the obstacle-free region of the region, and each equilibrium point includes a corresponding controller driving the object to the equilibrium point, such that each controller includes a corresponding state partition. Designing the controller and the corresponding state partition, based on the obstacle-free region around the equilibrium point, to produce a collection of controllers and corresponding equilibrium points and corresponding state partitions, that connect the initial location with the final location. Determining actuator commands at time T using a controller corresponding to a state partition that includes the location of the object at time T, and the resulting sequence over a period of time of actuator commands, moves the object.
