ITERATIVE LEARNING CONTROL METHOD FOR MULTI-MASS VEHICLE CONVOY TRAVELLING SYSTEM

WIPO Patent Application WO/2022/262362

A1

The present invention relates to the field of iterative learning control. Disclosed is an iterative learning control method for a multi-mass vehicle convoy travelling system. The method comprises: firstly, discretizing a multi-mass train dynamics equation by using a finite difference method to obtain a partial recursion equation, and then converting the partial recursion equation into a spatial interconnection system model; secondly, converting the spatial interconnection system model into an equivalent one-dimensional dynamic model by using a lifting technology, and designing an iterative learning control law on the basis of a state observer in order to compensate for input time lag; and thirdly, converting a controlled object into an equivalent discrete repetition process according to the iterative learning control law, and converting a controller synthesis problem into a linear matrix inequality on the basis of stability analysis of the repetition process. The method is simple and easy to implement, solves the problem of system output response lag caused by input time lag, considers the structural uncertainty of the system, and has good control performance and robustness.
