Experimental study presented in “Delay Compensation of Tilt Sensors Based on MEMS Accelerometer Using Data Fusion Technique” by M. Ghanbari and M. J. Yazdanpanah is commented. It seems that some of the reported results are affected by errors related to mechanical imperfections of the applied test apparatus, what might have influenced determination of parameters of models of the applied complementary and Kalman filters. Appropriate modifications of the test apparatus are proposed. An alternative method of processing the experimental data is suggested.
