A plant is only as steady as its base-layer control. Cerasus audits every loop for performance and health, fixes the valves and configurations that undermine control, and tunes with methods that give predictable, stable response.
Loop assessment measures how each PID loop actually performs — time in manual, oscillation, variability, valve travel and stiction — and diagnoses why. Tuning then sets controller parameters (Kc, Ti, Td) from an identified process model using lambda/IMC or other model-based methods, with a chosen speed of response.
The hidden value is in the diagnosis: many 'tuning problems' are valve, filter or configuration problems, and tuning alone will not fix them.
