Research on Stopping Control Methods of Electric Locomotive Under Different Working Conditions
In order to improve the stability and accuracy of electric locomotive parking,accurate braking is realized,a double closed-loop vector control permanent magnet synchronous motor based on fuzzy PID current loop and torque loop is adopted.At different initial stopping speeds,the maximum error of 10 stopping distances is-0.16 m.At different parking distances,the maximum error of 11 parking distances is-0.19 m.At different gradients,the maximum error of 7 stopping distances is 0.21 m.The above errors are all less than±0.3 m,indicating that this stopping control method can effectively realize accurate stopping of electric locomotives.
