    摘要:

    现有矿井提升装备恒减速安全制动装备主要采用模拟控制,在紧急制动过程中存在平稳性差、减速度超调严重等问题,因此提出软硬件冗余全数字控制的恒减速控制系统。该系统采用了一用一备的液压控制回路;在电气方面,选用两套PLC300控制器以实现控制算法的软硬件冗余,采用两套PLC1200控制两套电液伺服比例阀,实现液压控制系统的硬件冗余。利用仿真软件SimulationX对所研制样机进行建模,以完善控制器算法和参数。最后对样机进行测试,结果表明所提方案具有良好的性能。

    Abstract:

    The analog controls a mode used for the most of mine hoist constant deceleration braking systems creates to some problems which has the poor stationary and serious deceleration overshoot during the process of emergency barking. Therefore, a fully digital control method with software and hardware redundant for constant deceleration braking systems is presented in this paper. The system adopts two sets of hydraulic control circuits, one of which is spare. In electrical control, two sets of PLC300 are chosen to realize software and hardware redundancy of control algorithm and two sets of PLC1200 are adopted to control electrohydraulic serve proportional valve to realize hardware redundancy of hydraulic control system. The hydraulic and electrical simulation models are established with the simulationX to improve algorithm and parameters of the controller. A prototype is manufactured and tested on site. The results show that the proposed scheme has good performance.
