This paper presents a robust hybrid fault‐tolerant optimal predictive control (HFTPC), for an
industrial robot arm under hybrid (electric and pneumatic) actuator faults and/or varying time …

A new six-degree-of-freedom dynamic model is established to more completely characterize
the physical features of a bridge crane. Previous works on this type of crane control system …

Hydraulic crawler excavators have been widely used for construction in industry, mining,
and agriculture because of their special ability to work on weak soil support. However, the …

At present, there are many efforts put into high performance tracking control of the pneumatic
position servo system that have achieved considerable results, but the state constraints are …

A ridable ballbot has unstable underactuated dynamics with nonholonomic velocity
constraints and input coupling case. Such a robot can carry people and move in any …

In this study, a novel multiphase converged control structure with a switching mechanism is
established based on the fundamentals of the fast-terminal sliding mode. This control …

Taking a direct-drive volume control (DDVC) electro-hydraulic servo system as the research
object and aiming at the problems of the servo motor torque fluctuation, high-precision …

Aiming at the problem of the coexistence of matching and mismatching uncertainties in
electro-hydraulic servo systems, disturbance observers and a backstepping sliding mode …

Spherical robots are the mobile robots with the locomoting by displacing its centre of gravity
to generate torque and rotate itself. Therefore, the angle of the main body inside the robot …

Gas turbine engines (GTE) are widely used in military and industrial applications. Accurate
modeling is mandatory to advance GTE control. The present article investigates …
