Title of Speech: Fast and Precision Motion Control for Industrial Positioning Devices
Abstract: Fast-response and high-precision motion control is one of indispensable techniques in a wide variety of high performance mechatronic systems including micro and/or nano scale motion, such as data storage devices, machine tools, manufacturing tools for electronics components, and industrial robots, from the standpoints of high productivity, high quality of products, and total cost reduction. In those applications, the required specifications in the motion performance, e.g. response/settling time, trajectory/settling accuracy, etc., should be sufficiently achieved. In addition, the robustness against disturbances and/or uncertainties, the mechanical vibration suppression, and the adaptation capability against variations in mechanisms should be essential properties to be provided in the performance.
The keynote speech presents the fast and precision motion control techniques, where a 2-degrees-of-freedom (2-DoF) control framework is especially handled as one of practical and/or promising approaches to improve the motion performance. Actual issues and relevant solutions for each component in the 2-DoF control structure are clarified, and then, one of examples, a 2-DoF controller design for robust vibration suppression positioning, is presented as an application to industrial high precision positioning devices. In this speech, especially, a command shaping technique with robust performance is discussing for typical industrial manufactural machines, considering mechanical vibration suppression, input saturation, and plant perturbations.

Title of Speech: Experience-Based Lecture of Vibration and Control Engineering Using Dual Scale Experiments
Abstract: This plenary talk presents an experience-based lecture style for vibration and control engineering in Nagoya University. In the proposed style, experiments of the free vibration using a seismic building with vibration isolation layer and advanced vibration control using an effective small device are provided in combination. In the first trial of this lecture style in 2015, two hundreds of second-year students felt the free vibration of the five-story building with a weight of 5,600 ton inside the building and witnessed the mechanism of the isolation layer. To follow the demonstration experimentally, we have built a small experimental system. The device is composed of a vibration component (flexible structure) corresponding to the building and a cart with a handle corresponding to the ground. They are connected via a linear actuator corresponding to the isolation layer. Students oscillate the cart and observe the motion of the vibration component. In addition, the system has virtual reality cameras to attract students' interest and reduce the size gap influence of the real building and the small experimental system. The second lecture was conducted in 2017. A questionnaire showed that 100% of students valued the lecture style as useful. Since 90% of students valued that providing largescale demonstration lecture and the second lecture in combination as useful, the proposed style achieved a certain result.

Title of Speech: Adaptive Double Hidden Layer Neural Network Sliding Mode Control of Active Power Filter
Abstract: In this paper, a full-regulated recurrent neural structure which has double hidden layer neural network (DHLRNN) is designed. Then, an adaptive global sliding mode controller based on the double hidden layer recurrent neural network is proposed to improve the performance of harmonic current compensation and system robustness of Active Power Filter (APF). Six parameters of the double hidden layer recurrent neural designed in this paper can adaptively stabilize to their best values according to different inputs. Compared with the gener RBF neural network with single hidden layer, the double hidden layer neural network can improve the accuracy and generalization ability of the network, reduce the number of network weights and accelerate the network training speed owing to the strong fitting and presentation ability of two-layer activation functions. The feedback neural network plays the significant role in possessing associative memory and rapid system convergence. Simulation and experiment demonstrated that the satisfactory performance of proposed controller under both dynamic and steady state operations, including robustness, fast response, and small overshoot for harmonic suppression.
