topquark12 8c9e12587f fix simulation math, provided simulation control loop is stable and passes test, reaching simulation cycle limit before settling fails test 2020-12-28 17:38:10 +08:00
topquark12 7c013ff4a4 PID fixes 
Flipped error calculation method to correct behavior of kP and kI terms.

Added anti integral windup to integral handling.

Changed how the i and integral term is calculated, to prevent old kI settings from affecting the current i term calculation when kI is being tuned. Especially noticable when kI is set from a non-zero value to zero.
