| Title | 363: Current versus voltage control of plasma shape | ||

| Description: | |||
| Experimental Approach/Plan: | 1. Plasma current and position control only. First use the voltage control scheme for the RZIP control. Then shift to the coil current scheme. Gain matrix with proper PID operation is used to generate coil current requirement. PID operation on the difference between the required and measured coil currents generates the commands to the PF power supplies. For the current control scheme, first apply the measured coil currents in the voltage control scheme as the feed forward portion of the current demand and gradually remove this feed forward component.
2. Emulate EAST reference shape and make plasma shape controlled. Apply the PF power supply voltage controlled first and then shift to be current controlled. Using feed forward current more or less just like what was done in the first step. | ||
