High
Density Hard Disk Drive Control
Bits of information are stored on and retrieved from computer disk drives using a magnetic read/write head. Today’s information storage industry is forced to move toward micro hard-disk-drives (micro-drives) for laptop computers and smaller hand-held devices as well as high performance drives with extreme large storage capacity and fast data retrieval/storage time. This trend has posted a great challenge to the design of servo controllers for the moving parts of the information storage devices... |

Control of Electro-hydraulic Systems
Hydraulic systems have been widely used in industry due to the ability to apply very large forces and torque; examples like excavators, hydraulic robot manipulators, injection molding machine, and flight simulator. However, the dynamics of hydraulic systems are highly nonlinear and the system may be subjected to non-smooth and discontinuous nonlinearities due to the control input saturation, directional change of valve opening, friction, and valve overlap. In addition, hydraulic systems also have large extent of model uncertainties (e.g., large changes in load and the large variations in the parameters such as bulk modulus). These factors make the precision control of hydraulic systems extremely difficult... |

Automotive Controls
The increasing demand for driving safety makes the drive and brake-by-wire the only option for future vehicles. Drive/Brake-by-wire provides the hardware possible of individually controlling each wheel with a response time much shorter than human drivers. Thus, through intelligent and precise coordinated control of four individual brake systems, traditionally unavoidable accidents such as skidding due to the loss of grasping of a particular wheel can be prevented... |
