Realized the automatic control of temperature by using the fuzzy-PID control algorithm in the ARM, system structure is more simple and improves the control efficiency greatly, realizes intention for fully automated test. Last by taking simulation through matlab, the stability of temperature control markedly improved than the original, and the response time shortened by 20 seconds.Keywords: fuzzy control; PID control; ARM; temperature relay1¶ȼ̵ҪĻǼ̵Ķ¶Ⱥͻָ¶¶ȼ̵ ⷽˣ˹ˮ¶ȼƷַҪѴʱ;Ҽ ľȷȲ[2].ʮϵͳ˵ӼԺɱȽƵ ׶ϵͳڵ·ṹ,ЧֻһЩƾҪϵ͵ij .ǶʽʵֶԼ¶ȵĿѡԼ۱ȸڵԵARM Cortex-M3[5],ʵ¶ȼ̵Զ.¶ȿ㷨Ƚϵ͵Ĵͳ PID㷨,㷨רܿ㷨PID㷨Ϊ㷨ȶ Խǿŵ㷺Ӧâ?ſѧIJϽ,¶ȼ̵ӦõijԽ ԽǶ¶ȼ̵ƷҪҲԽԽ,Ҫ¶ȼ̵ иӾȷļ,¶ȼϵͳѡΪʵĿ㷨ԵΪҪ PID㷨ڴͺԿԼʱԵҪϵIJ 㷨PID㷨Դʵֲ߿,¶ȿƵľȷȺӦٶ.
