Optimal input selection method and device for hierarchical system, medium and product

The invention discloses a hierarchical system optimal input selection method and device, a medium and a product, and relates to the technical field of automatic control, and the method comprises the steps: initializing a model matrix, and defining a cost function; the model matrix comprises a sparse state transition matrix and a sparse input matrix; creating constraint parameters; the constraint parameters comprise an equality constraint parameter, an inequality constraint parameter and an input upper limit constraint parameter, the equality constraint parameter comprises an equality constraint matrix and an equality constraint vector, and the inequality constraint parameter comprises an inequality constraint matrix and an inequality constraint vector; the input upper limit constraint parameters comprise an input upper limit constraint matrix and an input upper limit constraint vector; based on the sparse state transition matrix, a strong communication component is searched, and hierarchical representation of
