Description 550-556
Present study consists the diagnosis of thruster fault condition using statistical
design of experiment. Fault in thruster can cause deviation in process
parameter, i.e. current load which could interfere with the propulsion system
and overall system operation. The faulty conditions are demonstrated by blocked
ducting. Variations of current load due to several conditions e.g. normal and
faulty are studied using analysis of variance (ANOVA) and factorial design.
Two-Factor factorial design is used to analyze the means in each factor. The
two factors are the armature voltage and thruster condition. Tukey’s method is
used to test all pair wise means in a single factor i.e. thruster condition in
order to confirm the significant variation for
each condition. Result from the experiment shows that the null hypothesis H0 for both Two-Factor factorial
design and Tukey’s test are rejected and the alternate hypothesis H1 is accepted. This
indicates that the current loads for each pair are varying and all means in
thruster condition factor are significantly different.
