|---|---|---|
Closed loop output error identification algorithms (7, 9)and recently developed algorithms for direct closed loop estimation of reduced order controllers (8) despite their diversity have in fact a unifying basic ground which will be enhanced. In this paper it is shown that the plant model identification in closed loop using closed loop output error identification algorithms and the direct estimation in closed loop of a reduced order controller feature a duality character. Basic schemes, algorithms and properties of the algorithms can be directly obtained by interchanging the plant model and the controller. Additional schemes and algorithms allowing a full coverage of the various possible identification and reduction criteria are given. The paper also will explore the coherence aspects in using closed loop plant model identification and direct estimation in closed loop of reduced order controllers. The following problem will be addressed: what closed loop plant model identification should be used when a criterion for con- troller reduction is given? |
