Summary Excerpt Details

Human balancing is an important issue in many fields of everyday life, such as walking, running, cycling, carrying objects and even standing. The understanding of the balancing process is very important, especially from the point of view of elderly people. However, there are a lot of open questions about the working principle of the neural system.

We focus on the mathematical modelling of the neural process, which flows in the human neurotic system during standing still. There are several approaches in the literature. One approach is to apply a linear compensator (such as PD, PID, PIDA) in the model. Besides, model based predictive controllers are also feasible, when the human acts using a pre-learned control input pattern in the certain situations.

In our study, we compare the operation of the two control approaches, by comparing stabilometry measures, such as typical vibration frequencies, average velocity of the center of mass of the body and maximum/average tilt angle.

Zusammenfassung der Kapitel (Chapter Summaries)

  • Introduction: This chapter introduces the importance of feedback control in science and engineering, highlighting human balancing as a prime example. It discusses the complexity of balancing, the various sensory inputs involved, and the crucial role of the brain in controlling movement. It also emphasizes the significance of research in this area, particularly for addressing the needs of an aging population.
  • Model of human balancing: This chapter details the mechanical model used to represent human balancing, focusing on the inverted pendulum as a simplified representation. It further explores different controller approaches, including PD controllers, PD controllers with dead-zone, and model-predictive energy-based controllers.
  • Measurement data and comparison with the simulations: This chapter presents the simulated and measured data obtained from the experiments. It then analyzes and compares the data based on stabilometry measures, such as typical vibration frequencies, average velocity of the center of mass, and maximum/average tilt angle.
