In this paper we present an event-based methodology for the control of the depth of hypnosis in general anesthesia. The control system is based on the implementation of an event generator with strong noise filtering capabilities together with a PIDPlus controller and considers both the administration of propofol and remifentanil in order to obtained a desired level of the bispectral index scale. Simulation...
In this paper we propose a new event detector for control systems with a PIplus controller. Its main feature is its capability of filtering the noise in a very effective way, by generating a quantized signal. Practical guidelines are given for the selection of the parameters. Simulation results show the efficacy of the technique and that it outperforms the use of standard use of a Butterworth low-pass...
The growth of power consumption of autonomous objects requires creation of new powerful and energy-efficient converters. This paper describes a new version of the autonomous power generation system alternating current and constant frequency with better energy-efficiency based on three-level converters. The results of computer simulation in the software package POWERSIM 9.0 are presented in the work...
The validity of mathematical model as basis to research the boiler-turbine coordinated control system will direct impact the research result. Based on the energy conversation law, the Bell- Astrom model has deeply analyzed in this paper. The mathematical deducing offer a method applied to analyze and distinguish a mathematical model. Moreover it has provide that the mathematical model much more accord...
Wind turbine systems have strong nonlinear multivariable with many uncertain factors and disturbances. Making use of the sliding mode variable structure control strategy, letting the system capability as the sliding mode function. The system of loop-speed-control and loop-position-control are designed base on the sliding mode variable structure control, which can make the system quick, steady and...
A delay-locked loop of multi-band selector with wide-locking range and low power dissipation is presented. The architecture of the proposed delay-locked loop consists of phase frequency detector, charge pump, band selector, multi-control delay line, and start-up circuit. The multi-band selector is used to extend operation frequency of delay-locked loop by switching the multi-control delay line. The...
MPSS simulates the behavior of a high traffic transaction processing system. An effective use of MPSS is the analysis of the impact of exclusive control of system resources over multiple processes. MPSS consists of a control process and multiple application processes. The control process is designed to simulate a transaction processing monitor. It initiates and oversees multiple application processes...
