温室草莓灰霉病T-S模糊控制模型

摘要

Combined Logistic model of biological population with the fuzziness of Botrytis cinerea, the corre-sponding T-S fuzzy model for the Botrytis cinerea of greenhouse strawberry is proposed. According to the sta-bility theory of Lyapunov, some sufficient conditions which make the T-S fuzzy model stable are obtained. Fur-ther, the controllers which make the model global stable are designed to realize the prevention and control for the Botrytis cinerea of greenhouse strawberry. Finally, the simulations are carried out to prove the correctness of the conclusion by means of Matlab software.%基于生物种群的Logistic增长模型,结合灰霉病病菌的模糊性,建立温室草莓灰霉病病菌的T-S模糊模型.根据Lyapunov稳定性定理,给出所建T-S模糊控制系统稳定的充分条件,并设计控制器,使模型全局稳定,实现对温室草莓灰霉病的预防与控制.最后利用Matlab进行数值仿真,以验证结论的正确性.
