This paper proposes a two-degree-of-freedom control systems design using a preview feedforward controller called zero phase error tracking controller (ZPETC) to improvethe tracking performanceof the disturbance observer-basedPredictive Functional Control (PFC) systems. To this end, we derive a pulse transfer function representation of the PFC controller, which is used for the design of ZPETC, and show some properties of the PFC controller. Then a disturbance observer-based PFC system combined with ZPETC is designed. Several experiments using a single axis table drive system are conducted to validate the effectiveness of the proposed control method. The experimental results show that the tracking error is dramatically reduced compared to the previously-developeddisturbance observer-based PFC.

In disaster areas, rescue work by humans is extremely difficult and dangerous. Therefore, rescue work using rescue robots in place of humans is attracting attention. This study specifically examines peristaltic crawling, the movement technique used by earthworms, because it can enable movement through narrow spaces and because it can provide stable movement even in various difficult environments. Moreover, we designed each part of the robot based on required specifications and developed a real robot. We present results of motion experiments conducted with robot movement on level ground.

In recent years, in consideration for danger of secondary disaster at disaster areas, development of rescue robots has been expected. We have paid attention to the mechanism of the peristalsis performed by earthworms and developed a robot using the mechanism. In this research, we developed a robot which recreates the motion of the muscles of earthworms using two kinds of actuators. The feature of this mechanism is that the robot is always able to move a fixed distance even if the space is narrow. In this paper, we propose the mechanism of the robot and consider the three moving patterns of the robot.

This paper addresses position and path-tracking problems of robot manipulators subject to constraints on both the magnitude and difference of the control input. Along with the model predictive control (MPC), the disturbance observer (DOB) is used to compensate for disturbances and nominalize the plant dynamics. To constrain the total control input, which is the sum of the MPC output and DOB output, we adopt time-varying input constraints and construct a useful structure of the combined DOB-MPC system. The effectiveness of the proposed control scheme is validated through a few experiments using a real two-link manipulator.
