This graduation project is about a stage lighting control system based on Siemens s7200. In this design, the number of stage lamps is large, and the characteristics of the flicker are varied. Combined with the advantages of PLC control, the control of 28 lights on stage is realized through PLC. Different flicker effects are achieved by controlling the time relay. Through the simulation, it is proved that PLC control can control the lighting of stage stably, and achieve the desired design goal. Secondly, in view of the lifting stage synchronization control system of big inertia, nonlinear and timevarying characteristics, bined with the advantages of conventional PID control, PID control algorithm is proposed for elevator stage of synchronous control system. MATLAB simulation shows that the PID control algorithm can meet the requirements of system synchronization, speed and stability. Key words: stage lighting， PLC control， synchronous lift 太原科技大學畢業(yè)設(shè)計 1 第 1 章 緒論 引言 隨著科學技術(shù)的不斷發(fā)展以及人們審美水平的不斷上升。 I 目 錄 摘要 ......................................................................................................................................................I ABSTRACT .......................................................................................................................................
