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(tǒng)前向通道增益對控制穩(wěn)定性和控制結(jié)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(tǒng)設(shè)計至少要包括單片機(jī)存儲器及i o擴(kuò)展,人機(jī)通道,前向通道及后向通道的的軟硬件設(shè)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(huán)伺服系統(tǒng)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(tǒng)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(jī)采用at89c51單片機(jī), a / d轉(zhuǎn)換采用12位轉(zhuǎn)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(shè)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(tǒng)硬件的設(shè)計上,設(shè)計了前向通道的信號調(diào)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(jī)等模塊的驅(qū)動電路。
