Treatment of Jw-Axis Model-Matching Transformation Zeros in the Optimal H Squared and H Infinity Control Designs

摘要

A model-matching transformation (MMT) zero is defined as a rank-deficiency condition which prevents an Hsq or H sup inf optimal control problem from being transformed into an equivalent model-matching problem. By imposing saturation constraints and accounting for additive instrument noise in the sensor and actuator signals, all MMT zeros can be eliminated. This is attained at the cost of making the underlying Hsq or H sup inf optimization problem generically 4-block.
