【Abstract】 To address the difficulties for adjusting parameters and the dynamically adapting problems for traditional PID controller, a PID control system based on memristors(M-PID) was designed, where the memristor model was based on the varactor diodes. The proposed M-PID control system could automatically update the parameters. Based upon theoretical derivation, not only the Multisim simulation was carried out, but also the circuit experiment was conducted. The control results of sinusoidal and triangular wave signals were observed. In addition, experiments were also performed on the pulsed signals based on the existing research results. The results show that the setting time of the M-PID control system is 10.724 μs, which is better than that of the traditional PID system. It is a new method to realize intelligent PID controller.更多还原
