Servomotors have found widespread application in many areas, such as manufacturing,
robotics, automation, and others. Thus, the control of servomotors is divided into various …

Reducing the system order and requiring precise knowledge of the system states and
mechanical parameters are of crucial significance for suppressing the mechanical …

To address the defects of the traditional adaptive notch filter, a parameter self-tuning notch
filter based on an improved Broyden–Fletcher–Goldfarb–Shanno and a simplified linear …

In the servo system, input signals often easily reach a state of saturation, resulting in the
discrepancies between the controller's output and the actual application requirements. To …

This study focuses on the problem of disturbance rejection in nonlinear repetitive-control
systems. The conventional method for rejecting disturbance based on equivalent-input …

Committed to the fact that the cogging torque of permanent magnet synchronous motors
(PMSMs) under low-speed operation severely aggravates the speed ripple as well as the …

In the fields of industrial production or safety monitoring, wireless sensor networks are often
content with unreliable and time-varying channels that are susceptible to interference …

When the operating conditions are changed suddenly, the model mismatch for the servo
system using model-based methods occurs during the identification convergence, which will …
