Young, Peter CSumislawska, M2015-12-10July 11-139783902823069http://hdl.handle.net/1885/68687This paper demonstrates the feasibility of a new approach to system inversion and input signal estimation based on the exploitation of non-minimal state space feedback control system design methods that can be applied to non-minimum phase and unstable systems. The real and simulated examples demonstrate its practical utility and show that it has particular relevance in a hydrological systems context.Keywords: Hydrological system; Input estimation; Input signal; Non-minimum phase; State-space feedback; System inversion; Systems approach; Unstable system; Adaptive control systems201210.3182/20120711-3-BE-2027.001002016-02-24
