    摘要: Disclosed are industrial polyester fibers and preparation thereof. The industrial polyester fibers are prepared from polyester chips ranging, in intrinsic viscosity, from 1.00 to 1.15 with a moisture content of 30 ppm or less. The chips are produced through the solid-polymerization of polyester low chips comprising an antimony compound at a residual content of 200-400 ppm as calculated by antimony metal. The polyester chips are melt-spun through a nozzle contained within a pack. In the pack, the polyester chips were melted at 290-300 °C and extruded to conduits of polymer dispersing plates, each conduit having a static mixer composed of at least three units. The filaments released from the nozzle, are oiled at an O.P.U. of 0.3-0.8% with a 10-30%, aqueous emulsion oiling agent prepared from a raw solution which comprises dialkyl-thio-diester, and fatty acid monoester or alkyl alkylate at an amount of 50 weight % or greater with the dialkyl-thio-diester amounting to at least 30 weight % of the raw solution. The multifilament yarn is taken up at a speed of 2,000-3,300 m/min to obtain undrawn yarn ranging, in intrinsic viscosity, from 0.95 to 1.02 and, in orientation degree, from 40x10 -3 to 90x10 -3. The undrawn yarns are subjected to multi-step drawing to give drawn yarns which are of high tenacity and low shrinkage.

    摘要: The present invention provides a method for operating dual controller which monitors the state of a dual controller to determine whether the dual controller is faulty and enables operation thereof with a controller in a normal state. An operation method of a dual controller according to the present invention dq-converts control command output values of first and second controllers to calculate rates of change in dq conversion values and dq-converts feedback input values, fed back to the first and second controllers, to calculate average rates of change in dq conversion values. When the average rates of change in the dq conversion values for the control command output values and the average rates of change in the dq conversion values for the feedback input values for the respective first and second controllers are identical, the corresponding controller is determined to be in a normal state, and to be in a faulty state otherwise. According to the results of the determination, the controller in the faulty state is set to a standby state and the controller in the normal state is set to an active state.
