Notes:
The precision control of the injection process in micro injection molding demands precisetracking of the moment that melt front passes through the nozzle so that accurate prediction of theamount of melt being injected into the mould can be achieved. The tracking accuracy, to largeextent, depends on the processing of pressure signals followed by the identification of the criticalmoment that melt front reaches the nozzle. A new adaptive Kalman filter was introduced in thisstudy to calculate and predict the amount of melt injected. The filter eliminated the delay error andwas more robust than other filters. The adaptive Kalman filter switches between two Qs for steadystateand transient estimations, allowing resetting of the Kalman gain so that convergence isspeeded up in calculations. Experimental and simulation results prove the effectiveness of themethod proposed
