Robust Anti-Windup Control Design for PID Controllers–Theory and Experimental Verification
This paper addresses an approximation-based anti-windup (AW) control strategy for suppressing the windup effect caused by actuator saturation nonlinearity in proportional–integral–derivative (PID) controlled systems. The effect of actuator constraint is firstly regarded as a disturbance imported to the PID controller. The external disturbance can then be modeled by a linear differential equatio...

متن کاملRobust closed-loop control of induction and maintenance of propofol anesthesia in children.
BACKGROUND During closed-loop control, a drug infusion is continually adjusted according to a measure of clinical effect (e.g., an electroencephalographic depth of hypnosis (DoH) index). Inconsistency in population-derived pediatric pharmacokinetic/pharmacodynamic models and the large interpatient variability observed in children suggest a role for closed-loop control in optimizing the administ...
متن کاملEvaluation of propofol anesthesia in morbidly obese children and adolescents
BACKGROUND Poor characterization of propofol pharmacokinetics and pharmacodynamics in the morbidly obese (MO) pediatric population poses dosing challenges. This study was conducted to evaluate propofol total intravenous anesthesia (TIVA) in this population. METHODS After IRB approval, a prospective study was conducted in 20 MO children and adolescents undergoing laparoscopic surgery under cli...
متن کاملA gain-scheduled PID controller for propofol dosing in anesthesia
A gain-scheduled proportional-integral-derivative controller is proposed for the closed-loop dosing of propofol in anesthesia (with the bispectral index as a controlled variable). In particular, it is shown that a different tuning of the parameters should be used during the infusion and maintenance phases. Further, the role of the noise filter is investigated.
