Detailed Description

Structure to hold PID controller data

  • kp, ki, and kd are the gain coefficients of the proportional, integral and derivative terms respectively
  • prev_error - the error computed last time step to be used for derivative computation
  • accum_error - the total accumulated error of the system to be used for integral computation
  • prev_time - the last time the PID was updated, to be used for integral and derivative computations
