linear tracing
2.In this paper, history of ADRC is introduced, ADRC and its three componentsincluding linear tracing differentiator, extended state observer and the structure ofnonlinear error feedback control regulation are deeply analyzed and simulationmodels of quadratic nonlinear tracing differentiator, thress order extended stateobserver and quadratic linear ADRC are given.
3.In accordance with the feature of non-linear and time varying for ferment process,the neural network model is established to estimate the concentration of product. Based on this model,PSO algorithm is applied to reach the optimum and optimal trajectory for the ferment process of L-Asparaginase Ⅱ. By online adjustment,the tracing control to the optimal trajectory is implemented.
4.Using a ray-tracing code combined with a fast two-dimensional relativistic quasi-linear Fokker-Planck solver,the 2D equation is discretized in momentum space using an implicit 5-point stencil and solved using the NAG library routine D03UAF. Numerical simulation of synergy of LHW and FW for the FTU(Frascati Tokamak Upgrade) plasmas has been carried out.
