Adaptive PID control of high-voltage power supply for ECRH on RBF network

The high negative voltage power supply for the ECRH (Electron Cyclotron Resonance Heating) is a key component of the cyclotron. This system is the nonlinear system with the high requirements on static and dynamic performance. It is difficult to control well using traditional PID controller, so a new intelligent method is adopted to turn PID parameters base on RBF Network. Simulation results show that the system has good dynamic and static performance. The steady-state accuracy is less than 0.3%, adjustment time is less than 200μs. And the system has strong robustness and adaptive capacity based on RBF.
