Design of position-controlled linear actuator systems using hydraulic drive design assistant (HyDDAs)
The design process of hydraulic motion control systems requires a high level of expertise that is generally rarely found. The expert system package Hydraulic Drive Design Assistant (HyDDAs) has been developed to provide a framework for comprehensive system design support based on methods of artificial intelligence. This paper focuses on the application of HyDDAs to the design of position-controlled cylinder drives. Structural, procedural, and rule-based means of knowledge representation in the area of hydraulic servo systems are introduced. Architecture and functionality of the HyDDAs expert system framework are explained, and a custom-made software tool for knowledge acquisition is presented. The framework is complemented by a knowledge base that comprises the methodical knowledge and experience that is necessary to perform the given design task. The methodology used for the design of valve-controlled linear actuator systems is lined out, concentrating on static and dynamic system behavior as well as servohydraulic control technology. Controller selection is aided by performance indices as a means of assessing system suitability. The demonstrated efficacy of HyDDAs for design support contributes to making the process of servohydraulic drive system design more accessible and reliable, also for inexperienced users.
