8.6 Tuning the Control Algorithm
This option should only be used by control systems engineers who are familiar with tuning PID loops.
This is not intended for the casual user. Changing these values may result in the system oscillating
without settling on the set point or never reaching the set point at all. See Section 21, Appendix 2 for
more information and theory on PID control.
The MPC VECTOR allows users to tune the motor control algorithm to speed up or slow down the MPC
VECTOR response time. This is done by adjusting the PID Controller parameter coefficients.
The user may adjust the Proportional coefficient, k
p
, the Integration coefficient, k
i
, and the Derivative
coefficient, k
d
, independently. The user may also view and modify the sampling period of the control loop, t
s
.
