With the control weight in an LQ optimal control system fixed,the state weighting matrix is parametrized in terms of a set of freevariables and the closed-loop eigenvalues of the control system. Basedon this parametrization, an algorithmic procedure is proposed to deter-mine the state weighting matrix and the free variables by matrixtransformation. Meanwhile, by using the solved free variables, theoptimal feedback gain matrix K can also be obtained without solving thealgebraic Riccati equation.展开更多

文摘In this report,the PMA-induced chromosomeaberration rates (CAR) of cultured peripheralblood cells of 10 untreated esophageal cancer and14 normal subjects were studied.At the same time,the levels of SOD of midium ultrafiltrates fromPMA-treated cultures after 1 ed 48 h were deter-minated.

文摘In this paper, solution to the LQ inverse problem has been pre-sented. With the control weight in an LQ optimal control system fixed,the state weighting matrix is parametrized in terms of a set of freevariables and the closed-loop eigenvalues of the control system. Basedon this parametrization, an algorithmic procedure is proposed to deter-mine the state weighting matrix and the free variables by matrixtransformation. Meanwhile, by using the solved free variables, theoptimal feedback gain matrix K can also be obtained without solving thealgebraic Riccati equation.
