The results showed that the relative errors between identifications and calibration parameters of the experiments can be controlled within 20%, which means HOCC not only has good robustness to noise but also solves the problem produced by the missing data of the current of inductance. This work provided a benchmark for the measurement of instrument parameters of Chua's circuit, and could further apply on the parameter identification of other complicated networks. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2019-021
