| Description
| - Tento článek je zaměřen na vývoj řídicího systému pro DVD-video přehrávače. Pro DVD přehrávače s vyššími rychlostmi, interní/externí perturbace a nelinearity akčních členů jsou významné a požadavky na kvalitu řízení jsou náročné. A combined pole placement/sensitivity function metoda byla použita pro redukci externích poruch a defektů disku. Zobecněná zásoba stability systému je vypočtena k ověření stability systému. Model nejistoty, založený na parametrickém popisu, slouží k validaci regulátorů. Výsledkky této analýzy byly testovány na reálném sytému v laboratořích firmy STMicroelectronics. (cs)
- The problem considered in this paper is the robust controller design for the focus control loop of DVD-video drive. For low-speed players, is known that this problem can be solved by means of simple lead-lag regulators. For high-speed players the disturbance rejection is more difficult problem than for CD players because of higher performance requirements. The control scheme proposed here is based on the design of robust digital controllers using the combined pole placement/sensitivity function sshaping method to reduce the effect of repetitive disturbances. Controller order reduction is performed to allow its practical implementation. Experimental results, obtained on a real system in STMicroelectronics laboratories, illustrate the performance of the proposed algorithms for the focus control loop.
