Harvesting adequate power for actuation in implanted biomedical devices using an electromagnetic field is a challenging task. Previous attempts to actuate and control deep implants have proven difficult and challenging. In this paper we propose an alternative solution to remote powering and actuation of implanted biomedical devices using a novel hybrid(More)
In this paper, a new methodology for feed forward-feedback control system design is proposed. Initially, the concept of control equilibrium point is introduced. Using this concept, the steady state control command is determined so as to maintain the desired situation of the system. Non-model-based feed forward control law is conducted on this basis using an(More)
This article addresses sensorless control of a piezoelectric tube actuator to avoid the expense and practical limits of displacement sensors in nanopositioning. Three electrical signals have been used to estimate displacement: the piezoelectric voltage, the induced voltage and the sensing voltage. In this work, the piezoelectric voltage was employed to(More)
