A vibration controller based on wavelet neural network (WNN) is designed for jacket-type offshore platforms with time delay. The offshore platform is regarded as a single-degree-of-freedom (SDOF) system while wave forces are irregular disturbances, and we can rebuild them in the context of Morison equation and wave theory. To reduce the vibration, a WNN vibration controller is designed based on a...
This paper focuses on the problem of vibration control for vehicle active suspension systems. According to the characteristics of the independent suspension system in vehicles, we decompose the suspension system into two subsystems from the perspective of practical. To complete the design of the vibration controller, we design a decoupling control law with respect to disturbances and a stabilization...
This paper considers the vibration control for vehicle active suspension systems with road disturbances. A mathematical model of road disturbances is established. Using the quasi-internal model control, a vibration control law is designed. The controller consists of a quasi-internal model compensator and a stabilization controller. The quasi-internal model compensator ensures control precision of...
This paper considers how to make full use of the known input feature information, to seek the effective control method for networked control systems with disturbances. Using priori knowledge of disturbances, we present a new quasi-internal model control approach. The controller design process is divided into two steps: quasi-internal model compensator design and stabilization controller design. The...
