Rotation and translation measurement

A position determining system (PDS)(100) or multiple parameters measurement system (MPMS)(300) particularly useful for translation and rotation measurement of objects having up to five degrees of freedom. A light source (122, 302) provides light beams (124, 304) into at least two channels. Each channel may include an interferometer (310), reflective target (110, 314), beam splitter (128, 312), detector (132, 316), and receiver (318). In concert, the detectors (132, 316) sense horizontal, vertical, and roll position and the receivers (318) sense longitudinal and yaw position change. Optionally, modulation can be imposed on the light beams (124, 304) and phase-sensitive synchronous demodulation used to enhance accuracy.

Engine idle speed target rotation speed control method

The invention relates to an engine idle speed target rotation speed control method. The method comprises the following steps that a plurality of target idle speeds are obtained according to combustioncontrol requirements, the maximum one of the target idle speeds is taken and subjected to change rate limiting, and a combustion target idle speed n<SetpointComb> is obtained; a plurality of target idle speeds are obtained according to load control requirements, the maximum one of the target idle speeds is taken, and a load target idle speed n<SetpointLoad> is obtained; the sum of the combustiontarget idle speed n<SetpointComb> and the load target idle speed n<SetpointLoad> is calculated to obtain a target idle speed initial value n<SetpointRaw>; the target idle speed initial value n<SetpointRaw> is subjected to dynamic regulation to obtain a dynamic target idle speed rotation speed n<SetpointDyn>; the dynamic target idle speed rotation speed n<SetpointDyn> is subjected to smoothing treatment to obtain a final target idle speed rotation speed n<SetpointFinal>; and the idle speed of an engine is set to the final target idle speed rotation speed n<SetpointFinal>. According to the engine idle speed target rotation speed control method provided by the invention, sufficient consideration is performed at the final target idle speed rotation speed of the engine, the situation that the rotation speed is too high or too low can be avoided, and in addition, the stability of idle speed closed-loop control is high.
