This invention discloses a dynamic modeling method for a three-orthogonal magnetic reluctance translational magnetic bearing. Based on the equivalent magnetic circuit method, magnetic circuit analysis is performed. Utilizing Ohm's law for magnetic circuits, a single-pole electromagnetic force model of the three-orthogonal magnetic bearing is obtained. Using the lateral edge of a right-angled regular triangular pyramid as a reference, the magnetic bearing's three magnetic poles are evenly distributed circumferentially to construct an orthogonal model magnetic circuit. By analyzing the geometric characteristics of the three-orthogonal magnetic bearing, a coordinate transformation matrix (direction cosine matrix) for the electromagnetic force coordinate system and the position coordinate system is constructed. When the magnetically levitated mover is subjected to external disturbance, the current flowing through the magnetic bearing coil winding is changed according to the change in mover displacement, thereby achieving mover control. The dynamic modeling method for the three-orthogonal magnetic reluctance translational magnetic bearing described in this invention can realize three-degree-of-freedom translation and preset position levitation of the platform on which the magnetic bearing is mounted, and has broad application prospects in the field of attitude control technology for novel spacecraft.

The invention discloses a herbicidal composition and its application, and relates to the field of pesticides. The composition comprises the following raw materials in percentage by weight: 5-60% of propanil, 1-40% of triclopyr, 0.1-22% of picloram, 3-15% of dispersant, 2-10% of wetting agent, 10-40% of disintegrant, and the rest of filler. The water-dispersible granules of the ternary composite composition of the invention can ultimately solve the problems of disintegration and suspension after heat storage by screening suitable dispersants, wetting agents and fillers. The prepared water-dispersible granules have the characteristics of fast disintegration, good dispersibility, high suspension rate and good stability, and are more conducive to the exertion of drug efficacy.
