| Abstract: | 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. |
| Keywords: | hydraulic elevator electrohydraulic proportional speed control intelligent control expert control integral control performance figure |
