Abstract

Basic characteristics of high-speed railway pantograph system, it is required to ensure the stability and safety of pantograph contact during the operation of Electric locomotive, the characteristic is that the current transmission between the pantograph and the catenary is stable, real time monitoring and storage of parameters, the mechanical vibration error of the pantograph and catenary is small, and the operation curve adjustment is fast. Firstly, analyze the design indicators and curve characteristics of the operating parameters of the high-speed pantograph system, propose the structural characteristics of mechanical vibration of pantograph-catenary; Secondly, analyze the principle of mechanical vibration of the pantograph and catenary, as well as the parameter prediction models of DMC, establish a flowchart based on open-loop predictive control algorithm; DMC (Dynamic Matrix Control) is an open-loop control for clustering optimization curves. Its mechanism is to use the dynamic parameter indicators of the pantograph and catenary system as reference inputs, optimization strategy based on online detection and curve adjustment of mechanical vibration of pantograph and catenary. Quantitative relationship between algorithm and system performance, guide the debugging of design parameters in applications. Finally, four sets of pantograph net experiments were detected and analyzed through on-site instruments, theoretical simulation comparison. The optimal solution is obtained based on the DMC open-loop control method, which is superior to GPC (Generalized Predictive Control) generalized closed-loop feedback control.
