Description: The Current Controller block uses the error between reference current signals and measured current signals to generate modulation indices for three-phase motor voltages.
All inputs are divided by their respective full-scale values to derive normalized values. For example, – id_n = id_ref/C_fs, where id_ref is the user input and C_fs is the full-scale current.
currentcontroller_Kp (V/A): <tbs. need description> Also you need to write using normal English. For example, the should be Current Controller Kp
currentcontroller_wi (rad/s): <TBS, need description>Also you need to write using normal English. For example, the should be Current Controller wi
Fullscale Current (A): <tbs need description>
Fullscale Freq (Hz): <tbs need description>
Fullscale Voltage (V): <tbs need description>
Max Duty Cycle: Specifies the upper and lower limit on modulation indices.
User current ramp: Safety limits to avoid sudden jerks in the input values <tbs. Also you need to be consistent in use of initial capitalization. For example, this should be User Current Ramp>
User frequency ramp: <TBS> Also you need to be consistent in use of initial capitalization. For example, this should be User Frequency Ramp
