This paper focuses on modeling and identification of environmental climates inside naturally ventilated tropical greenhouse (NVTG). The NVTG climate model is an essential tool for developing the climate control system. A real-time wireless monitoring system for measuring prototyped NVTG environmental climates for chili plantation was developed. The variables to estimate the NVTG outputs variables namely internal relative humidity and internal temperature are external temperature, external humidity, irradiance, and wind speed. Modeling based on mathematical equation as well as using system identification (SI) technique is outlined. The paper also highlights on SI procedure namely data acquisition, identified model structure that represents NVTG using NARX and ARX model structures, parameter estimation technique, and model validation. Simulation studies reveal that linear and nonlinear polynomial models are able to model and simulate the NVTG performance.
