摘要:
目前LADRC 参数整定常采用带宽法,对非最小相位系统控制有一定局限。针对这一问题,利用广义自抗扰控制( GADRC) 来整定LADRC 参数。该方法借鉴常规ADRC 带宽整定法的思路,利用模型信息,适用于所有线性系统的ADRC 参数整定。为了克服得到的LADRC 控制器阶数较高的问题,采用频域下的控制器降阶,得到低阶LADRC。所提整定方法不受控制器和观测器带宽配置的限制,便于工程实现。将该方法应用于有自平衡能力和无自平衡能力的水轮机负荷频率控制系统的设计,仿真结果表明,由GADRC 整定LADRC 可以获得较好的控制性能且系统抗干扰能力好,鲁棒性强。
Abstract:
Linear active disturbance rejection approach ( LADRC) was applied to the load frequency control ( LFC) of hydraulic power systems. LADRC parameters were generally tuned via two bandwidths,which is difficult for non-minimum phase systems. To improve the control performance of the conventional LADRC,a generalized ADRC ( GADRC) approach was adopted. The GADRC method is similar to the conventional LADRC tuning method. The full model information of the controlled plant was utilized,and better control performance was achieved. However it usually results in a high-order controller. To overcome the problem,an approximation method in frequency domain was used to obtain a low-order LADRC. The proposed method can break the limitation of the bandwidth tuning. Simulations on hydraulic power systems show that LADRC tuned through GADRC can achieve better performance and the closedloop system has strong disturbance rejection capability and robustness.
