Engine speed controller having PI gains set by engine speed and engine speed error

A PI control strategy controls engine speed to an engine speed set-point. A proportional map (36) is populated with data values to be used in calculating the P component of the strategy. An integral map (38) is populated with data values to be used in calculating the I component. Each data value in the maps is correlated with a speed data value representing engine speed (N) and a speed error data value representing the difference between engine speed and engine speed set-point (N_DIF_MAX_LIM). Values for proportional and integral components are selected from the respective maps by processing current engine speed data and current engine speed error data. The strategy uses the values from the maps for controlling engine speed to the speed set-point. Data values from other maps (20 and 24; or 22 and 26) modify the selected values from the proportional and integral maps (36, 38) for transmission type, transmission gear, and engine temperature.

Detector configuration for interferometric distance measurement

ActiveUS20070229841A1Accurate measurementReduction and elimination of differential phase shiftInterferometersUsing optical meansDifferential phasePhase shifted
A phase difference detector generates a plurality of signals from an input beam including orthogonal, linearly polarized object and reference beam components. The detector may be configured such that as the reference and object beam components traverse the detector, phase shifts due to surface interactions are made as similar as possible between the s-components of the reference object beams, and between the p-components of the reference and object beams. Various outputs may be formed by interfering p-components exclusively, or s-components exclusively, negating errors that may otherwise arise due to differential phase shifts between p- and s-components. Phase-shifting elements in the detector may receive beams from beam splitting surfaces where the transmissive differential phase shift between p- and s-components is adjusted to insignificance.

Polarized light irradiation apparatus

A polarized light irradiation apparatus, having at least two plane mirrors, is constructed to prevent reduction of the extinction ratio of the polarized light that irradiates a substrate when there is a change of the direction of polarization of the polarized light that is incident on a reflecting mirror. This is accomplished by forming a protection layer on the surface of the second plane mirror, and selecting the material and optical thickness of the layer in accordance with the angle of incidence and wavelength of the polarized light so that the difference DELTA of the phase shifts of the polarization P component and the polarization S component emerging from the second plane mirror satisfies the condition that DELTA<=±20°. By doing this, there will be no reduction of the extinction ratio of the polarized light that irradiates the substrate W if there is a change in the polarization direction of the polarized light that is incident on the second plane mirror.
