Struct ZieglerNichols 

Source 
pub struct ZieglerNichols {
    pub ku: f64,
    pub tu: f64,
}
Expand description

Ziegler-Nichols auto-tuning: compute PID gains from ultimate gain and period.

Given the ultimate gain Ku and ultimate period Tu (oscillation period at marginal stability), this struct computes classic Ziegler-Nichols PID parameters.

Fields§

§ku: f64

Ultimate gain (marginal stability gain).

§tu: f64

Ultimate period (oscillation period at Ku, in seconds).

Implementations§

Source§

impl ZieglerNichols

Source

pub fn new(ku: f64, tu: f64) -> Self

Create a Ziegler-Nichols tuner from ultimate gain and period.

Source

pub fn pid(&self) -> ZnGains

Classic Ziegler-Nichols PID gains.

Source

pub fn pi(&self) -> ZnGains

Ziegler-Nichols PI gains (no derivative).

Source

pub fn p_only(&self) -> ZnGains

Ziegler-Nichols P-only gain.

Source

pub fn simc(&self) -> ZnGains
