Outline of Final Research Achievements

The communication delay became delay time and negatively affects, mainly steady-state deviation, in the control system through the wireless communication network. In order to compensate the steady-state deviation caused by variable delay time, Variable-scaling Communication Disturbance Observer (VSCDOB) and High-Pass Filter Communication Disturbance Observer (HPF CDOB) were proposed. The steady-state deviation was improved with proposed methods. Especially, the transient response was simultaneously improved using HPF CDOB. The wireless communication control technique of actuators was established.
