【摘要】：為克服傳統(tǒng)變槳距系統(tǒng)存在的能耗高、控制機(jī)構(gòu)復(fù)雜的缺點,提出直驅(qū)液壓泵控馬達(dá)變槳距系統(tǒng)。采用可變速伺服電機(jī)驅(qū)動定量泵的閉式液壓回路結(jié)構(gòu),針對變槳系統(tǒng)自身存在的非線性與參數(shù)不確定等特性,基于反演遞推(backstepping)技術(shù),結(jié)合自適應(yīng)算法,設(shè)計自適應(yīng)反演控制器,通過構(gòu)造Lyapunov函數(shù)推證穩(wěn)定性,并在此基礎(chǔ)上,采用實測數(shù)據(jù)進(jìn)行仿真驗算。結(jié)果表明,系統(tǒng)具有良好的自適應(yīng)性、抗干擾性,有較高的變槳距控制精度,能較好地穩(wěn)定機(jī)組輸出功率。
[Abstract]:In order to overcome the disadvantages of high energy consumption and complex control mechanism in traditional variable pitch system, a direct drive hydraulic pump controlled motor variable pitch system is proposed. The closed hydraulic loop structure of quantitative pump driven by variable speed servo motor is adopted. In view of the characteristics of nonlinearity and parameter uncertainty existing in the propeller system itself, the adaptive inverse controller is designed based on the inverse recursive backstepping technique and the adaptive algorithm. The stability is proved by constructing Lyapunov function, and on the basis of this, the real data is used to simulate and check the stability. The results show that the system has good adaptability, anti-interference, high pitch control precision, and can stabilize the output power of the unit.
