| Summary: | A dispensing system is used in a materials-mixing plant to provide accurate blend ratios
in producing the desired end-use product. The AIS-based (Artificial Immune Systems) fine tuning of
dispensing parameters is proposed by optimizing the components of dispensing time and stopping
time delay to obtain constant and accurate reading from the precision balance scale. Based on the
new dispensing sequence, experimental tests had been carried out using different materials with
varying viscosities. The results indicate that the combination of both PWM and AIS techniques
would minimize overshoot while exhibiting lower steady-state error and faster response time. These
are important in order to overcome the limitations of the conventional volumetric dispensing and
manual parameter tuning presently applied in the dispensing system used in the coatings industry. |
