A comparative evaluation of DRE integration algorithms for real-time simulation of biologically activated sludge process

摘要: Abstract An activated sludge process is considered in this work for comparative tests of new integration algorithms. Based on the configuration and kinetics heterotrophic bacterial growth, mathematical model has been derived form a state ordinary differential equation system. The system describing may be both stiff non-stiff operator's control changes oxygen feeding flow rate. In work, discrete response equivalent (DRE) algorithms are proposed simulation runs with fixed step size, which independent dynamics (this possibility due to self-adaptive features algorithms). have compared most other frequently used show that, among algorithms, only DRE fixed, arbitrarily chosen size during simulation.
