Hybrid Fuzzy Controller for Temperature Process
Abstract: Temperature control is a process in which change of temperature of a space is measured or otherwise detected, and the passage of heat energy into or out of the space is adjusted to achieve a desired average temperature. Control of such a temperature process is achieved by means of a closed loop circuit in contrast to an open loop in the case of measurement only. To accurately control process temperature …
