The alternating servo control PLC speed governor of turbine adopts the intellectual alternating current servo driver system of full digital alternating current servo motor and driver with leading screw installations, and a direct link mechanical hydraulic follower system that its main pressure valve is directly controlled by the alternating current servo driving system.

By using the basic theories of the mechanical system dynamics, the author creates the mechanics model of the engineer-drive system and disclosures the inherent characters of the dual -mass flywheel as for the torsional damp of the auto s drive system by the dynamic performance parameter obtained by the modal analysis.

Control design for underactuated mechanical systems: a survey;

Control of underactuated mechanical systems is currently an active and challenging field of research due to the lack of control inputs and their broad applications in robotics, aerospace vehicles, and transportation vehicles.

A coordinates and control change was designed for a class of underactuated mechanical systems to transform the dynamics into cascade nonlinear systems in strict feedforward form,and based on the derived cascade nonlinear system in strict feedforward form,the nested saturation control scheme was proposed for the class of underactuated mechanical systems.

The bond graph modeling method can easily draw the bond graph of a mechanical rotation system.
