Nonlinear observer of the non-spatial dynamics of anthracnose: Case study of coffee berry disease

作者：

Highlights：

• An improved model of the dynamics of coffee berry disease is provided;

• The fruit volume, the rot volume and the disease severity are considered;

• The only outputs of the system are the fruit volume and the rot volume;

• The control strategies are usually based on disease severity which is not observable;

• Disease severity is efficiently estimated through the construction of an observer.
