Adaptive Covariance Kalman Filtering and Nonlinear Decoupling Control via Feedback Linearization for a Three-Tank Process

Bambang L. Widjiantoro, Katherin Indriawati, Moh Kamalul Wafi

Exact linearization and decoupling control let a three-tank system track dynamic liquid level references, with an adaptive Kalman filter estimating the nonlinear states.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The designed methods have successfully traced the dynamic reference signals. The adaptive system noise Kalman filter (AKF) algorithm yields a rewarding prediction of the true non-linear system.

C2weakest assumption

The exact linearization and decoupling control remain valid under some (unspecified) assumptions about the system model and operating conditions.

C3one line summary

Adaptive Kalman filtering with exact linearization and decoupling control tracks dynamic references and estimates the nonlinear three-tank system.
