The effect of the gain in forward channel on the stability and result of control scheme have also been illustrated by numerical simulation 文中還通過仿真算例分析了系統前向通道增益對控制穩定性和控制結果的影響。
But , the former is not so easy , especially the anomalous plane . this paper plans to design a planimeter to solute this problem 本系統設計至少要包括單片機存儲器及i o擴展,人機通道,前向通道及后向通道的的軟硬件設計。
The influences of the driving error and hysterisis error to the closed servo system were analyzed and their calculation methods have been put forward 分析閉環伺服系統前向通道上精密傳動裝置的傳動誤差和回程誤差對伺服系統性能的影響,提出計算方法。
Hardware controller uses the at89c51 monolithic integrated circuit , a / d transformation uses 12 bit transformations chips max187 , has completed the design of a front channel for sampling and processing the simulated signal 其中硬件單片機采用at89c51單片機, a / d轉換采用12位轉換芯片max187 ,完成了模擬信號從采樣到處理的整個前向通道設計。
On basis of software engineering , adopts the modular designing method , and makes full use of the functions what the mcu offers , such as a / d function , interrupt function , pwm function , and software timer function 在系統硬件的設計上,設計了前向通道的信號調理電路、鍵盤模塊、液晶顯示模塊、大容量存儲器、串行通訊以及打印機等模塊的驅動電路。
In the paper the constitution of the testing system in the tilting train is discussed , as well as the design of the front access , the subsystems performing the function of interruption , resetting , saving , communication and debugging 文中不僅對擺式列車測試系統的組成進行了討論,并圍繞dsp設計了測試系統的前向通道,中斷、復位子系統,存儲了系統,通信子系統和調試子系統。
This instrument hopes to control the step - motor regularly , and collects the datum of the distance between the laser sensor and the wall simultaneously , then calculates area according to the theory of triangle , finally sums up all the area and makes the output 本系統前向通道信號由激光傳感器提供,后向通道信號發給步進電機、傳感器,由于是旋轉式測量,必須控制激光發射信號的通斷和步進電機的步距角,否則測出的值是無法計算的。
The hardware of system is used sensor and signal conditioning circuit to collect the signal and communication with the computer using the pci2013 . for the undulation of temperature and driven current will influence the testing result , they need to be invariableness during testing 系統硬件以傳感器和相應的信號調理電路作為前向通道拾取被測信號,利用基于pci高速總線的pci2013數據采集卡和串口模塊實現與計算機的數據傳輸和命令通訊。
