考虑到自适应控制不仅能抑制外界干扰及环境、参数变化,且能有效地消除模型化误差这一特性,为了进一步简化控制算法,缩短采样周期,提高控制性能。本文根据δ—MRACS设计理论,构成一阶自适应控制器,并应用到液压控制系统中。通过大量的仿真及在线实时控制试验,说明该设计方法的有效性和实用性。
Considering that adaptive control can not only suppress external disturbance, environment and parameter changes, but also effectively eliminate the modeling error. In order to further simplify the control algorithm, shorten the sampling period and improve the control performance. Based on the δ-MRACS design theory, this paper constructs a first-order adaptive controller and applies it to the hydraulic control system. Through a large number of simulation and online real-time control experiments, the effectiveness and practicability of this design method are illustrated.
