Parameter Selection Guidelines for a Parabolic Sliding Mode Filter Based on Frequency and Time Domain Characteristics

Figure 9

Time response of filter (1a)–(1c) with normalized input 𝑢(𝑡)=0.01+0.003𝜀(𝑡)s², which is a step input corrupted by white Gaussian noise. Here, the response of filter (1a)–(1c) with 𝛼=1 refers to that of filter (4a)–(4c).
