adaptive observation model的用法和样例：
- The concept of targeted or adaptive observation was established and tested operationally during the field experiments.
- The system consists of four parts: light source model, diamond model, observation model and light tracing module.
- Conclusion: Observable model could be economically established with dose of 20 mg/kg CsA.
- Numerical simulation example reveals the AFO is an adaptive observer with strong tracking properties, which can accurately estimate the unknown time-varying parameters in addition to nonlinear state function.
