Title:
CUSTOMIZED HARMONIC REPETITIVE CONTROLLER AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/143319
Kind Code:
A1
Abstract:
A customized harmonic repetitive controller and a control method, belonging to the field of industrial-controlled repetitive controllers. The repetitive controller uses a periodic signal generator composed of three time delay modules and a positive feedforward gain module as a whole to constitute a forward path, and constructs the internal model of the periodic signal in the form of an output positive feedback, so that the structure thereof conforms to the standard internal model construction method. The present invention has the capability of expanding an order, greatly improves the flexibility of the controller, increases the speed at which the controller eliminates disturbances, has a simply structure, and is easy to design. A further expanded h-order (nk±m) harmonic repetitive controller (h≥2) covers various existing high-order repetitive controllers, and provides a unified form, having universality.
