Predictive control of free calcium oxide based on improved echo state network
an improved on-line echo state network predictive control model is proposed for the problem that the traditional predictive control method has long adjustment time and low control precision. Therefore
we firstly combine the L1-norm constrained recursive least squares method with the echo state network to construct an on-line prediction model to address these issues. Then
the structure of predictive control model is constructed based on the improved prediction model of echo state network. And particle swarm optimization (PSO) algorithm with global optimization capability is utilized for rolling to ensure that the actual output follows the setting value of the controlled variable quickly
accurately and smoothly. Finally
the simulation prediction experiments of the free calcium oxide content in the cement burning system are conducted using the improved predictive control model. The results show that the improved predictive control model has good performance and application prospects.
