Unsaturated proportional output calculator

A proportional output uses the specified signed gain and bias before actuator saturation or limits.

Units
u=ubias+Kp×eu = u_{\text{bias}} + K_{p} \times e

Worked example

Given

  • ubiasu_{\text{bias}} = 40 %
  • KpK_{p} = 6 %/Δ°F
  • ee = 3 Δ°F
u=40+6×3=58u = 40 + 6 \times 3 = 58
