Abstract :
A method of relay feedback testing is developed. This method can overcome the shortcomings of traditional relay feedback and can be used to extract multiple-point frequency characteristics. Furthermore, based on nonlinear optimization, a frequency domain identification algorithm is proposed. Simulation shows an excellent result
