Structure‐induced low‐sensitivity design of sampled data and digital ladder filters using delta discrete‐time operator

Abstract

The concept of the delta discrete-time operator-based doubly terminated twopair (ladder) is discussed here for use in sampled-data and digital filter design.The two-pair filter utilizes traditional backward Euler and forward Euler integrators, is lossless under scaling (LUS), and possesses good magnitude sensitiv-

Sampling rate selection for multi‐loop cascade control systems in an optimal manner

“…The sampling rate yields thorough limitations in μ‐synthesis, as justified in [14]. Besides the shift operator approach to numerical systems, the difference operator approach has also been considered throughout the years, with improved quantization sensitivity, as demonstrated for $$\mathcal {H}_{\infty }$$ synthesis in [15], for high‐precision switching converters in [16], and ladder filter topologies [17].…”
