There is difference frequency measurement requirement for every part of pid regulating, difference between dynamic quality and static quality in response time and accuracy. according to these, it use the interrupt functions and high - speed counter of the simens s7 - 200 plc cpu226 basic unit and some peripheral circuit to measure frequency ; in software designed, the procedure frame of hydraulic - turbine governor and disperse process of parallel pid are analyzed, an improved pid algorithm is adopted to realize a pid regulation mode with variable structure and parameters ; the mechanical liquid - pressure system of the hydraulic - turbine governor is with electric - hydraulic converter unit of step motor. according to the drive character of five phase of response step motor, a variable frequency regulated voltage driver unit is designed in order to realize interface between plc and driver of step motor
本文利用s7 - 200plc自身的特點設計了頻率測量單元，根據pid調節各個環節的特點，以及調速器動態特性、靜態特性對頻率測量的實時性和精度要求的不同，利用s7 - 200plc基本單元中內置的高速計數器以及相應的外圍放大整形、分頻電路，實現了水輪發電機組頻率的測量；在軟體上，對微機調速器的整個程序框架、並聯pid的離散化過程進行了分析，選用改進的pid演算法實現了變參數、變結構的pid調節模式；調速器的機械液壓隨動系統具有步進電機電液轉換元件，採用五相反應式步進電機，根據其驅動特性設計了變頻調壓驅動器，實現plc與步進電機驅動器之間數字介面。 -
Based on the phenomenon, this paper introduces the multiple mega - sub controlled frame and its step design method, it can be generalized as the following approach : first, we look for the optimal stiffness of the sub structure to control the deformation of the mega structure under the wind load. second, we optimize the parameters of the turned mass damper ( tmd ) which are installed in the sub structure to have the acceleration be controlled, and then we realize the overall objective. at last this paper uses the ecpm method to optimize the parameters of tmd and utilize simulink to simulate the dynamical response
本文利用等效最優理論（ ecpm ）對tmd的參數進行了優化，利用simulink對復合結構進行了動態模擬，結果表明：附加安裝在子結構上的tmd並不會對主結構的動態特性產生大的影響，復合結構和減振結構一樣都可以較好的控制主結構位移響應，而且復合結構經優化后的tmd還較好的控制了子結構加速度響應，所以復合結構體系既可以提高結構的安全性，又可以滿足舒適度的要求，從而證明了本文提出的巨型框架復合減振結構是一種理想的超高層建築結構形式，其將具有廣闊的發展前景。
