Abstract

The invention provides a magnetically levitated train speed tracking method, which is applied to a magnetically levitated train speed tracking system, the system comprises a nonlinear active-disturbance-rejection controller, and the method comprises the following steps: calculating the tracking speed of a magnetically levitated train based on the operation parameters, the actual operation speed and the target tracking speed of the magnetically levitated train; controlling the maglev train to run at the tracking speed; wherein the gain factor and the compensation factor of the nonlinear active-disturbance-rejection controller are updated in real time by using an adaptive particle swarm algorithm based on the target tracking speed and the actual running speed of the magnetically levitated train. According to the maglev train speed tracking method, the global search capability is improved, the problems that a traditional particle swarm algorithm falls into local optimum and parameters of an active-disturbance-rejection controller are difficult to adjust are solved, the optimized parameters are suitable for different control objects, dependence on the control objects is reduced, and the speed tracking efficiency is improved. The nonlinear active-disturbance-rejection controller can realize speed tracking more accurately, and the speed tracking precision is improved.

Description

technical field [0001] The invention relates to the technical field of speed control of maglev trains, in particular to a speed tracking method for maglev trains and a machine-readable storage medium. Background technique [0002] As a relatively new means of transportation, the maglev train has been widely used in major cities in recent years. It uses electromagnetic attraction or electric repulsion to achieve non-contact suspension between the train and the track. The straddle-type maglev train has no direct contact with the track, and has many advantages such as fast start, high speed, low energy consumption, high comfort and low environmental pollution. In the course of its research, speed curve optimization and target speed curve tracking are one of the key technologies of maglev transportation system. [0003] At present, the control methods used for train speed curve tracking can be roughly divided into the following four categories: classical control methods, adapti...
