Abstract
H-infinity optimization techniques may be automated for multiple input multiple output (MIMO) control problems. In one implementation, a model may be received, where the model includes a plant portion that models elements that are to be controlled and a controller portion that models elements used to control the plant portion, the plant and controller portions of the model interacting with each other in a MIMO feedback configuration. Identification of tunable elements of the controller portion of the model may also be received. Requirements, relating to constraints of open or closed loop transfer functions of the model may also be received. Values for the adjustable parameters of the tunable elements may be calculated, where the calculation may be performed using non-smooth H-infinity optimization techniques and the calculation may be based on the model, the identification of the tunable elements, and the one or more requirements.
