Abstract
A method for a model predictive control (MPC) of a system determines entries of an approximate coefficient matrix only at locations identified in a map of locations as significant. The map of locations identifies each location of an entry in the approximate coefficient matrix as either significant or insignificant. The entries are determined using one or combination of an approximate coefficient function and an exact coefficient function. Next, the method determines a preconditioner using the approximate coefficient matrix and determines a solution vector by solving a matrix equation of the MPC with a coefficient matrix defined by an exact coefficient function at a current time step of a control using an iterative method with the preconditioner. The method generates a control signal for controlling the system using the solution vector.
