Research on Non-linear Excitation Controller Based on PLC
Liang Hong-fei · Electric Switchgear · 2010
The saftware and hardware forms and principle of a microcomputer′s excitation controller based on PLC are presented.For the control mothed,getting PID under control,it can combine advoantages which the terminal voltage of the generator is effecirely controlled with advantages that non-linear control can greatly improve dynamic stability of the system,achieving fine results.
