Abstract: A cross-coupling control method for moving beam of gantry machine tool is disclosed, which relates to the technical field of CNC machine tool control. The cross-coupling control method includes: Step 1: establishing a crossbeam dynamics model considering a ram on the crossbeam, and at the same time simplifying the model for an observer design; step 2: realizing a PID control parameter adjustment of motors at both ends in accordance with a method of parameter tuning of a unilateral servo control system; using a servo system with the same control parameters to jointly drive the crossbeam up and down, realizing the synchronous control and realizing PID control parameter tuning for both end motors. The disclosure not only reduces the synchronization error caused by the torsion of the crossbeam, but also solves the synchronization error caused by the asymmetric load on both sides, and improves the system robustness and stability.

Abstract: A specific antibody for detecting the blood brain barrier early injury of cerebral ischemic stroke is characterized by specifically identifying specifically identifying DHYETDYTTGGESC in degradation fragments of an occludin protein, but not identify ing the full-length occludin protein. Therefore, the antibody can be used for specifically detecting the blood brain barrier early injury of the cerebral ischemic stroke, and can eliminate the influence of the full-length occludin protein in serum on a detection result, so that the specificity and accuracy of detecting the blood brain barrier early injury of the cerebral ischemic stroke are significantly improved.
