Fuzzy Control
Design on the Algorithm of Elevator Group Control Based on Fuzzy Control
In recent years, elevator services become a must in higher buildings, so,one elevator couldn’t satisfy all needs of passengers in most of the cases. In order to cut down the waiting time,reduce power consumption, it is better to put many elevators together and monitor them together in reason. This optimization dispatching system to all the [...]
Design of a Humidity Control System of PEM Fuel Cell Based on Impedance Monitoring
PEMFC(Proton Exchange Membrane Fuel Cell) is a hermetical system,whose internal humidity is very important for the work efficiency and service life of fuel cell. If the internal humidity of fuel cell can be monitored even controlled,the economic losses caused by the damage of single cells in the abnormal situation will reduce greatly.Therefore,it has important practical [...]
The Design and Simulation of 25kW FCPS’s Temperature Management System
The temperature management system is a main technical of fuel cell power system(FCPS) development, especially for PEMFC engine, although it has great advantages, such as high efficiency, low working temperature, no pollution, fast start-up, high power density and so on, the heat of the PEMFC is non-reversible and nearly 40%～50% of the energy dissipation is [...]
