The invention discloses an active disturbance rejection control system of a platform screen door machine. The active disturbance rejection control system is composed of a door control unit DCU, a master control system PSC and a door machine unit which is composed of a power source module, a frequency changer module, a current sampling module and a brushless direct current motor module BLDCM. The door control unit DCU comprises two active disturbance rejection controllers ADRC, and a DSP microprocessor is adopted. A brushless direct current motor is equivalent to an integral series-connection object composed of two non-linear systems, and the two first-order active disturbance rejection controllers are used for achieving inner and outer loop control over the motor, rotating speed outer loop control and current inner loop control. The active disturbance rejection control system is applied, has the advantages of being high in response speed, high in control precision, and high in disturbance resisting capacity, and is very suitable for the platform screen door machine with the bad mounting environment.
Description
technical field [0001] The invention relates to the technical field of anti-disturbance control technology for subway shielded door operators, in particular to advanced control applied to shielded door operators, and belongs to the technical field of rail transit shielded door operator control equipment. Background technique [0002] The screen door system is a typical electromechanical product, which is installed on the edge of the subway, light rail and other transportation station platforms to isolate the station platform from the driving tunnel area. It is equipped with a sliding door that corresponds to the train door and can be opened and closed by multi-level control. continuous barrier. The installation of screen doors can reduce the energy consumption of the train station’s air-conditioning and ventilation system, and at the same time reduce the impact of the train’s operating noise and piston wind on the station, prevent accidents caused by people falling off the t...
