| Title | Self-sensing electromagnetic actuator |
| Objective | This is a continuation of a past part-time FYP project, which an experimental test rig and controller have been successfully and partially developed respectively to develop a self-sensing active electromagnetic actuator. |
| Scope | Active electromagnetic actuator requires some form of control based on feedback of the position of the suspended object. This feedback is required, fundamentally, in order to achieve stability, but more importantly, in order to permit tailoring of the actuator dynamics to achieve targeted system performance. Most electromagnetic actuator applications use feedback of the position along each axis of controlled force. In many potential applications of active electromagnetic actuators, the number of wires which must pass between the actuator controller and the components in the machine assembly needs to be minimized. A more substantial reduction in wires can be achieved by eliminating the discrete position sensing device and, instead, determining the position of the suspended object from information available in the electromagnet signals. This can be achieved by driving the coil windings with a bi-state switching amplifier which produces a substantial high frequency ripple. The amplitude of this ripple is a function of power supply voltage, switching duty cycle, and electromagnetic inductance - can be modulated to extract displacement position information. |
