Problems solved by technology

However, this method only discloses a common static levitation simulation platform, and maglev trains are generally divided into high-speed maglev trains and medium-low speed maglev trains. Due to their completely different operating modes and speeds, common static levitation simulations cannot be close to the actual Application scenarios lead to deviations in the research and design of control algorithms, causing adverse effects

Abstract

The invention relates to a levitation control simulation platform for high-speed and medium-low-speed maglev trains. The platform comprises a high-speed maglev train track magnetic coupling test bed,a medium-low-speed maglev train single-point levitation test bed and a DSPACE semi-physical simulation platform. The high-speed maglev train track magnetic coupling test bed is used for simulating track faults and track excitation conditions. The medium-low speed maglev train single-point levitation test bed is used for simulating the train load change situation caused by getting-on and getting-off of passengers in the running process of a medium-low speed maglev train. And a program runs in the DSPACE semi-physical simulation platform and is used for switching suspension algorithms and control parameters in the two test stands. Compared with the prior art, the platform is more suitable for the actual application conditions of two trains in the operation process, so that the magnetic levitation control algorithm researched and designed based on the platform is more accurate.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a suspension control simulation platform for high-speed and medium-low speed maglev trains. Background technique [0002] At present, due to the fact that the maglev train has no mechanical contact during operation, it greatly reduces mechanical wear and energy consumption, and has high environmental protection advantages. It is gradually called a new type of rail transportation. High-speed maglev trains can effectively break through the upper speed limit caused by wheel-rail contact, thereby achieving higher operating speeds with lower energy consumption. The lower mechanical noise (equivalent to the sound of a very high-end car) of the medium and low-speed maglev train during operation is unmatched by the existing light rail and ground rail transportation. [0003] The control algorithm of the maglev is the key technology in the maglev train. The control algorithm adjusts the outp...
