The aim of this study is to develop an optimal design and control for magnetic actuators in order to minimize the power consumption of the actuators.The power-minimizing design of actuators involves using permanent magnets for bias flux.We will focus on developing a unified and consistent design methodology that produces an optimal actuator geometry while satisfying the requirements.Controllers that minimize power consumption must be designed to guarantee enough force slew rate.We will develop a nonlinear controller that can minimize the power consumption without the sacrifice in dynamic capacity.
In order to obtain a power-minimizing actuator design and control,we will proceed our study as follows.?1st year:power-minimizing actuator design-Define a metric for power minimization-Obtain design equations based on electromagnetic theories-Provide an optimal design methodology for power minimization?2nd year:Verification of power-minimizing design-Build a prototype for the verification of power-minimizing design-Obtain dynamic simulation model-Obtain a power-minimizing controller through the dynamic simulation?3rd year:Implementation of power-minimizing magnetic bearing system-Evaluate the power minimizing performance through tests-Provide a verified optimal design for power minimization-Apply the power-minimizing design and control to existing systems
Recently,the emphasis on green technology and energy savings is as high as ever.With many advantages of magnetic bearing technology,it is important to have a power-minimizing design and control of magnetic bearings for them to be widely used in industrial applications such as flywheel energy storage systems,pumps,and satellite devices.The power-minimizing design can also be applied to other actuators such as piezoelectric or magnetostrictive actuators.Through this research,we expect to produce highly-trained graduate students who are proficient in electromechanical design and control theories.
