PID-based multi-mode oven heating control system design

A PID-based multi-mode oven heating control system is designed. Solve the current market of the traditional oven of the knob control method mode less and conventional control are large temperature deviation, low precision and other problems, it is difficult to achieve a better control effect. This work uses intelligent multi-segment PID control strategy, divides the algorithm design into multiple temperature rise sub-modules and designs a consistent control scheme for ovens of different equipment. The temperature control system designed in this paper can perform fast and slow heating in multiple modes, and the steady-state accuracy can be steadily controlled at ±2°C, while having good equipment consistency. The implementation of the multi-mode system and the experimental verification of the related performance are presented.
