Denoising sensors signals within mechatronic systems using EMD method

This paper presents different approaches for denoising sensor signals using the Empirical Mode Decomposition (EMD) technique. These techniques will be applied to denoise two real signals from the sensors of a test bench. For beginning, we mention the different types of noise that can affect various sensor signals from a test bench for aeronautical equipment during test. Then, we describe two approaches of denoising based on EMD algorithm, and we proposed a new method with is also based on the EMD algorithm. At the end of this article we discuss different results and comparing different methods, that allow removing or reduction of different types of noise.
