Active power filter with enhanced echo state network in radar power supply system

There have been concerns raised on load non-linearity as more and types are being introduced into the radar power supply system. The non-linear produces harmonic current while it seriously threatens normal safe operation environment of other system equipment. It can be difficult to design shunt active filter (APF) eliminate effect achieving stability reliability. This paper designs a hybrid optimization filter, which adopts enhanced echo state network (ESN) predict harmonics reduce delay problem in traditional control. prediction performance ESN is verified by simulation. modelling simulation APF completed Simulink, parameters reset according Furthermore, prototype based DSP TMS320F28335 was developed test whether theory feasible accurate. experimental results demonstrate that with has improved steady-state response rapid dynamic performance.
