Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] The online neural network inverse controller of the biological fermentation process of the present invention comprises two parts:
[0024] 1. Neural network inverse offline decoupling controller construction module 1.
[0025] For the uncertain two-input and two-output biological fermentation system, the right reversibility of the system is analyzed according to the inverse system theory, and the relative order of the system and the input and output variables of the inverse system are determined; the offline acquisition system data trains the neural network to approximate the inverse system, and the The trained neural network is connected in series with the controlled system to form a pseudo-linear composite system to realize the linearization and decoupling of the controlled system.
[0026] 2. Neural network inverse online learning module 2.
