摘　　要：以液压电梯为试验系统设计了基于专家控制器和仿人智能积分控制器的两级控制器,选取运行过程中一个阶段的误差积分作为系统运行性能评价指标,由专家控制器根据上次运行结果修正仿人智能积分控制器的有关参数,增强控制系统的自适应性和鲁棒性,通过试验验证了两级控制器的优越性和选取的系统运行性能评价指标的合理性.This two-level hierarchical controller designed for a hydraulic elevator test system consists of an intelligent integrator controller and an expert controller. The rationality of the two level hierarchical controller was proved by experiments. This two level hierarchical controller is superior to conventional controllers in that control self-adaptivity is enhanced, and the shortcomings of the integrator controller, and some negative influences on the system, such as complexity in modeling of the hydraulic control system and the non-linearity in the valve-controlled hydraulic cylinder system are avoided.
