Deposit Dimension Control with Using Single Neuron Self-learning PSD Controller During Spray Forming

摘要

A single neuron self-learning PSD controller is used to perform deposit dimension control during spray forming process. Simulation results show that control performance of PSD controller is satisfied, override and steady state error are zero at three predetermined target value, and corresponding response time is short too. PSD closed-loop control experimental results show that the average deposit thickness is 5.32 mm in steady period, average error is 0.18 mm between actual size and target value 5.5 mm, maximum error is 0.28 mm, and RMS(mean square root) of error is 0.23 mm. Both simulation and experiment show that PSD controller is suitable for deposit dimension control owing to its self-learning and intelligent characteristic.
