| Abstract: | A self optimizing rule fuzzy temperature controller implemented with LM74 and single chip processor is provided. The controller is applied in solidifying temperature control for epoxy nanocomposites preparation. By being composed of parameter self adjust algorithm with sensitivity factor and control performance evaluating algorithm, the controller can realize self optimizing control rules during the control process. For the info of rule adjusting can be inosculated in control output performance query table by the way of off line calculation, the controller can optimize control rule according to rule control state diversification without increase on line computational burden. The adaptability to parameter diversification is strengthened and dynamic performance of the controller is improved.The emulation and application in temperature control for epoxy nanocomposites preparation proved the effectiveness of the controller. |
