A method for milk powder spray-drying based on composite fuzzy control technology

The conventional PID control of most processes has good control effect and robustness. Without adaptive capacity and prone to elicit inertia delay, this method can only be applied in a special working condition. This paper puts forward a composite fuzzy PID control method based on the establishment of fuzzy rules and the compound of PID controller, as well as the cascade PID controller regulation in order to improve the system adaptability. By carrying out simulation and application in practice, the results showed that the composite fuzzy PID control method is superior to conventional PID control method.
