Patent ID: 7433743

Claim:
A method of controlling operation of a system, the system having a control input variable and a parameter that can be measured or estimated, the method comprising: constructing, off-line, a system operation model based on said control input variable and measurable parameter; constructing, off-line, an optimised explicit control solution comprising a value of said control input variable as a function of said parameter using parametric optimisation, in which the control solution comprises a co-ordinate space of at least one control variable value region comprising a control variable substitution value or a control variable value as a function of a parameter value, the co-ordinate being the parameter; storing the control solution on a data storage device; and during operation of the system, measuring or estimating a parameter of the system, obtaining the control input variable based on the measured or estimated parameter from the stored control solution, and inputting the obtained control input variable to the system to control operation of the system according to the measured or estimated parameter of the system.
