System Control Technology Based on Mathematical Methods
From mechanical to energy management systems
System control technology based on mathematical models can be applied to a wide range of fields, from mechanical systems such as four-wheeled robots to social systems such as energy management systems. At this laboratory, we are developing control methods for nonlinear and hybrid systems in particular.
Research
Many systems, such as manipulators and automobile engines, are nonlinear systems. Many conventional methods are created in view of individual cases. In this laboratory, we are developing a unified control method using control Lyapunov functions. As an example, we are considering the development of a four-wheeled robot running on a flat surface (Fig. 1). To achieve obstacle avoidance and movement to the target position, a pseudo height difference is set (Fig. 2). The obstacles are positioned high and the target is positioned low. This allows four-wheeled robots to achieve their control objectives with only one simple rule of following the low position.
Dynamical systems that include switching of dynamics are called hybrid systems, and are known to have many applications. Recently, we have been working on the application of hybrid systems to energy management systems. In particular, we are developing an electricity consumption model for consumers.Yuh Yamashita Professor
