Claim One:
1. A method of controlling a system having a plurality of state variables, so as to drive a process variable to a set point, the method comprising: (i) establishing a matrix chain comprised of a plurality of matrices, including a first matrix, at least one intermediate matrix, and a last matrix; wherein, each matrix generates an output based upon a plurality of inputs; wherein the inputs for the first matrix are state variables; wherein, for the at least one intermediate matrix, one input is the output from another matrix and another input is either a state variable or the output from another matrix; wherein, for the last matrix, at least one input is the output from another matrix, and the output of the last matrix is used to drive a control device that influences the process variable, and is further used as an input to either the first matrix or one of the at least one intermediate matrices; wherein, the matrix chain initially exhibits a degree of reflectivity that is a multiple of 360°; (ii) throughout the duration of controlling the system, inputting the state variables to the set of matrices; and (iii) throughout the duration of controlling the system, driving the control device with the output of the last matrix.
