The application discloses a microwave network assisted arbitrary-tap T-coil automatic synthesis method, comprising the following steps: firstly, using a microwave network to obtain the limit performance and the optimal topological structure of a circuit under the action of non-ideal factors; then, using the microwave network to consider the change range of the optimal inductance value when the quality factor and the coupling coefficient of the T-coil change in a reasonable range and to take the change range as an optimization area; then, according to the set index and process, combining the extended Wheeler formula and Latin hypercube sampling to obtain initial samples; then, using a Gaussian process regression to establish a proxy model of the concerned index and the parameters; finally, performing global optimization through a multi-path global optimization algorithm to obtain a target T-coil layout. It is verified that the method can efficiently synthesize the optimal T-coil.

This invention relates to a method for heterogeneous multi-vehicle collaborative path planning and operation control in fisheries under high sea states. The method includes: acquiring meteorological data from the Yellow and Bohai Seas; fitting the wave surface elevation spectrum from the meteorological data to a modified JONSWAP spectral model, while simultaneously decomposing bimodal features to calculate wave encounter frequency; defining a parameterized roll risk function based on the wave encounter frequency to generate a four-dimensional spatiotemporal cost map containing dynamic resonance risk regions; during the harvesting and transfer process, using an improved A algorithm to perform global path planning on the four-dimensional spatiotemporal cost map, generating a zigzag path; and during the live fish handover process in the harvesting and transfer process, establishing a cost function including a relative motion suppression term, and solving the fixed-berth and dynamic docking of multi-vehicle collaboration through rolling optimization. This invention solves the problems of neglecting wave-induced resonance risk and instability in multi-vehicle dynamic docking, significantly improving the safety and success rate of unmanned operations in large-scale offshore aquaculture facilities.
