Stage lighting control systems are increasingly important in theatrical performances , while the actual stage lighting control process , the expected projection of stage lighting scene with the actual projection scenarios there is a deviation , the need for stage lighting operator before the show or show a lot of commissioning work. Stage lighting projection enables more accurate and reduce the workload of the division of stage lighting , the subject of stage lighting control system , in order to find a new method to improve the stage lighting control system . The subject of the entire lighting control system , the clear research object as well as the range does not include the whole stage effect lighting stage lighting control system and the stage surface . The object is determined amount of input for iris , voltage and color the three control amount , the output of the multi-point of the pixel value of the three-color of the stage surface . Established through segmentation modeling method and stage lighting model and stage scene model by both push the mathematical model of the entire study . Controllability observability analysis , and two lights , three lights system controllability classification prove , and push much light situation Controllability mathematical model . Given observation point determination method of the determination method and the coefficient matrix of the system model . Control algorithm , improved stage lighting control system is designed to build a the laboratory stage lighting control system hardware analog circuit programming and the stage lighting simulation control system host computer interface and associated hardware circuit design . Through the analysis of the research object , come to the stage lighting control system for conditional controllability observability . By analyzing the types draw the Controllability measured point location , given the stage observation point method for determining the actual stage lighting control system . Simulation of the controlled object to build a feedback channel to provide a closed-loop control method for stage lighting control system . Build a the laboratory stage lighting simulation control system platform , and has laid a good foundation for further study after the stage lighting control system .
