| Abstract: | The features of temperature control system in electric cooker are introduced,and the math model of it is built.The drawbacks of temperature control in the conventional electric cooker are pointed out.In view of nutrition,the expected calefactive curve is suggested and the hardware circuit of temperature control system is designed.A control scheme of model deviation compensation is proposed.And,the principles and characters of this method are explained.Through the result of simulation in Matlab while taking electric cooker as controlled object,the method of model deviation compensation is proved to be reliable and precise in the application of the electric cooker's temperature control system.And the system errors are acceptable. |
