Intended learning outcomes

This course intends to give a detailed knowledge in hydraulic servo systems and its applications. The contents of the course covers both the mobile and industrial areas and theor different characteristics. After completing the course the student is expected to

• have knowledhe about component functionality and characteristics in the area os hydraulic servo systems.
• have knowledge about calculation methods and selection of components in high performance hydraulic servo systems
• have knowledge about control principals and control engineering methods with focus on controllability, stability and energy consumption of hydraulic servo systems
• have knowledge in measurement methods and computer usage for control and monitoring of hydraulic servo systems. 
• be able to model and analyse hydraulic servo systems with respect to performance, controllability and energy consumption.
• be able to apply calculation methods for component selections and system design.
• be able to perform measurements on components and systems. 

Course content

Extended theory on orifices, flow forces on valve elements and fluid physical properties. Modelling and simulation technology. Mathematical modelling of component and system dynamics. Control engineering analysis. Simulation of fluid systems dynamics. Proportional and servo valve designs and characteristics of different pilot and power stages. Servo systems for control of position, velocity and force. Multi-axis loads. Control strategies and dynamic characteristics. Sensor technologies and measurement methods for components specific to hydraulic servo systems.
