The magnetic attitude control laws for the microsatellite are presented from lyapunov function and the theory of fuzzy control 結(jié)合李亞普諾夫方法和模糊控制理論實(shí)現(xiàn)微小衛(wèi)星姿態(tài)磁控制。
The sliding mode function can be educed by constructing a lyapunov function . and the theory of fuzzy control is used to solve the sliding mode vibration problem 通過(guò)構(gòu)造李亞普諾夫函數(shù)得出切變流形函數(shù),得到一種開(kāi)關(guān)控制,利用模糊控制克服了常規(guī)開(kāi)關(guān)控制所固有的抖振現(xiàn)象。
( 2 ) the theory of fuzzy control resolves the control of electric machinery valve . the software design that is the module structure realizes the function of gas meter counting , inquiring and dealing with the malfunction ( 2 )模糊控制原理解決了電機(jī)閥的控制問(wèn)題,軟件設(shè)計(jì)中均采用模塊化設(shè)計(jì)結(jié)構(gòu),完成了燃?xì)獗淼挠?jì)費(fèi)功能以及故障的查詢和處理。
On the high layer , according to the theory of fuzzy control and expert system , so me software under the windows ' 98 is developed to carry on the intelligence fault diagnosis of motor and manage the field data with database 在上層模塊中,將模糊邏輯和專家系統(tǒng)結(jié)合建立了電機(jī)故障診斷智能系統(tǒng),開(kāi)發(fā)了windows環(huán)境下的控制及信息處理軟件,實(shí)現(xiàn)了對(duì)現(xiàn)場(chǎng)設(shè)備的進(jìn)行及時(shí)有效的監(jiān)控保護(hù)。
Aiming at the non - linear links such as time lag , inertia , dead time and saturation within the turbine regulating system , a fuzzy - immune - pid control system was designed based on a mutative scale chaos optimization method , the principium of immune feedback system and the theory of fuzzy control 摘要針對(duì)汽輪機(jī)調(diào)速系統(tǒng)中存在的時(shí)滯、慣性、死區(qū)和飽和等非線性環(huán)節(jié),采用模糊控制理論,結(jié)合免疫反饋機(jī)理,設(shè)計(jì)了基于變尺度混沌優(yōu)化策略的模糊免疫pid控制系統(tǒng)。
