Model-Based Control with Active Disturbance Rejection Algorithm for a Diesel Engine

To improve the speed control performance of a diesel engine, active disturbance rejection controller (ADRC) is designed by adding an arranging transition process to traditional PID controller, extracting differential signals reasonably, and adopting nonlinear combination error signals. The ADRC composed tracking differentiator (TD), extended state observer (ESO), feedback (NLSEF). Such constructed can adapt strong complicate working conditions engine for power generation. A simulation model built verify proposed ADRC, results are in good accordance with experimental results. further validate advantages improved TD. Meanwhile, comparisons carried out between ADRC. Results present that achieve better than both steady transient state. However, evidently on basis controller.
