【摘要】：为克服传统变桨距系统存在的能耗高、控制机构复杂的缺点,提出直驱液压泵控马达变桨距系统。采用可变速伺服电机驱动定量泵的闭式液压回路结构,针对变桨系统自身存在的非线性与参数不确定等特性,基于反演递推(backstepping)技术,结合自适应算法,设计自适应反演控制器,通过构造Lyapunov函数推证稳定性,并在此基础上,采用实测数据进行仿真验算。结果表明,系统具有良好的自适应性、抗干扰性,有较高的变桨距控制精度,能较好地稳定机组输出功率。
[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.
