7: Control Systems
| Command | Purpose |
|---|---|
| abort_autotune | Abort the autotuning process for a specified PID controller by setting flags or sending events to stop the tuning. |
| autotune |
Initiate tuning of a specified PID loop using the Ziegler-Nichols method (closed loop version – with relay caused oscillations). Note that the length of time to autotune is dependent on the period of oscillation of the system. |
| calc_gains | Compute control loop gains after auto-tuning. |
| chirp | Generate a swept-frequency cosine signal for system identification. |
| cmd_map_gen | Generate a controller’s command map and gain scale table based on specifications from a breakpoint table. |
| comp_ctrl |
Compute engine performance metrics including speed, torque, and acceleration rates for control operations. |
| ctrl_cfg_dsply | Display the new_state, action, subcode, index, and label information about the control configuration event when an event occurs. |
| ctrl_disp | Display control loop information for specified controllers or loops. |
| ctrl_params | Use this utility to set gains for control loops using parameters specified in a datafile. |
| ctrl_spec_converter | Use this script to create a new spec file that will work with the eng_ctrl_task in 6.3.x versions of CyFlex. |

| dy | Set the dyno controller to open loop mode and specify a target value with an optional ramp rate. |
| dy_gains | Set the proportional, integral, and derivative gains for the dyno control loop based on provided arguments. |
