The design of finite impulse response (FIR) filters and FIR-based differentiators is a popular
topic in the field of digital signal processing. FIR filters/differentiators are characterised by a …

In this paper, a predictive disturbance observer (DOB) design is presented. The proposed
DOB does not require a direct model of the process without the transport delay for prediction …

Numerical differentiation has been used to deal with many applications in physics and
engineering. Therefore, an appropriate approach is very important for the evaluation of …

A low-phase shift and real-time differential estimation is a common problem in the control
design. When linear phase shift filters are used at the system's output, a strong performance …

The problem of a significant phase shift in a control loop is posing a lot of challenges to the
control design. One of them is definitely the loss of performance with the increased phase …
