Here, its time-varying version is solved explicitly in terms of duality and operator theory. In particular, the optimum is shown to satisfy a time-varying allpass property. Moreover, optimal performance is given in terms of the norm of a bilinear form. The latter depends on a lower triangular projection and a multiplication operator defined on special versions of spaces of compact operators.<\/jats:p>","DOI":"10.1137\/080720267","type":"journal-article","created":{"date-parts":[[2010,1,29]],"date-time":"2010-01-29T18:15:53Z","timestamp":1264788953000},"page":"3354-3367","source":"Crossref","is-referenced-by-count":5,"title":["Time-Varying Optimal Disturbance Minimization in Presence of Plant Uncertainty"],"prefix":"10.1137","volume":"48","author":[{"given":"Seddik M.","family":"Djouadi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charalambos D.","family":"Charalambous","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"351","published-online":{"date-parts":[[2010,1,29]]},"reference":[{"key":"R1","first-page":"67","volume":"4","author":"Arveson W.","year":"1975","journal-title":"J.
