电液伺服控制理论

Learn the fundamental principles and applications of electro-hydraulic servo control systems through this comprehensive course. Master hydraulic amplification elements, hydraulic power components, and the transfer functions of four-way valve-controlled symmetric cylinders. Explore mechanical-hydraulic servo systems, including their composition, block diagrams, and stability analysis. Study electro-hydraulic servo valves, their classifications, and dynamic characteristics of force-feedback two-stage valves. Examine electro-hydraulic proportional valves and servo-proportional valves in detail. Gain practical knowledge in designing electro-hydraulic control systems, including position servo systems, force servo systems, and system correction methods. Apply theoretical concepts through real-world design examples, covering power source selection, amplifier specifications, and controller implementation. Complete hands-on exercises and problem-solving assignments throughout each chapter to reinforce understanding of electro-hydraulic servo control theory.
