PI controller scheme for charge balance in implantable electrical stimulators

Charge Counter for Performing Active Charge-balance in Miniaturized Electrical Stimulators

Functional Electrical Stimulation (FES) has been explored in order to restore the capabilities of the nervous system in patients that suffer from paralysis. This area of research and of clinical practice greatly benefits from any technological improvement yielding miniaturization. In this regard, we recently proposed and demonstrated an innovative electrical stimulation method based on implante...

Testing of electrical trancutaneous stimulators for suppressing pain.

As so many students of bioelectrical phenomenona frequently remind us, it was Luigi Galvani who first reported his experiments in applying electrical currents to contract the muscles of frogs and sheep . Numerous attempts have since been undertaken to utilize that phenomenon for a variety of therapeutic purposes, many of them quite successful . One of the most notable is the heart pacemaker. El...

Tuning methodology for a fuzzy PI controller

PI Controller Design for Actuator Preservation

New explicit design relations for setting the controller parameters in PI control of industrial processes are proposed. The objective is to obtain proper transient responses with smooth control actions minimizing the variations of the controller output, hence preserving actuators from untimely attrition. The use of the proposed relations is illustrated by tests on real processes. Copyright c ©2...
