This paper proposes a new observer gain tuning methodology to achieve a robust position control. The state observer is often used to estimate the state of the system. Generally, the observer gain is tuned by an evaluation function and the operator needs to arbitrarily select a weight function to obtain an optimal observer gain. This paper introduces a methodology for observer gain tuning using the...
This paper presents a novel disturbance compensation scheme to attenuate periodic disturbances on repetitive motion using permanent magnet linear synchronous motors (PMLSMs), and this scheme is called the periodical adaptive disturbance observer. The scheme is based on assumptions that all measured states and disturbances are periodic and repetitive when the tasks executed by PMLSM motion systems...
This paper analyzes the stability of acceleration-based bilateral control (ABC) using a disturbance observer (DOB) and a reaction force observer (RFOB) by considering the effect of environmental impedance and modeling error. ABC is one of the control method to enable highly precise transmission of haptic sensation between master and slave robots. Conventionally, ABC is analyzed by using slave side...
In the research about force sensorless bilateral control using piezoelectric cantilever, nonlinearities of piezoelectric constant and creep phenomenon has not been considered in reaction force observer (RFOB). Therefore, there are room for improvement of the performance of force estimation. In this paper, piezoelectric constant and creep phenomenon are modeled based on experimental results and built...
This paper proposes a periodic adaptive disturbance observer (PADOB) to control a PMLSM (Permanent Magnet Linear Synchronous Motor). The PADOB consists of a classical linear DOB and an adaptive mechanism which has been known as the periodic adaptive learning control (PALC). The key idea is to compensate parametric errors between the actual plant and the nominal model of DOB and disturbance forces...
Recently, remote communication technology such as telephone, radio and television is extensively developed. Haptic information is studied as the third multimedia information. Real-world haptics is getting attention as not only the principle for feedback of real-world haptic information in teleoperation but also the key technology for future human support. In order to control haptic information, the...
Recently, haptic information is studied as the third multimedia information. In order to control haptic information, bilateral control with a master slave system is used widely. Because the plural systems are handled, it becomes important to think of the connection condition among the systems. In this paper, the difference with unilateral control system and bilateral control system will be confirmed...
In this paper, creation of a new network model entitled as infinite mode networks is explained. Infinite mode networks intelligently governs any kind of systems by analyzing multi inputs and exerting multi outputs. They have a desired embedded internal function which roughly determines a route for the whole system to follow as a DNA does for biological systems. By this system, infinitely many error...
