在日常生活中，大脑必须适应多变的情况，这可能需要多种方法，包括通过内部身体图式形成预期协同作用和不同的控制策略。不稳定的任务特别具有挑战性，因为它会降低内部模型的预测能力，并进一步增强延迟感觉反馈的不稳定性。我们通过三个仿真研究来探索这个问题：A）二级倒立摆模型的混合控制，B）鞍状不稳定的双手镇定，C）全身焦点姿势动力学。模拟结果支持了大脑可以以面向任务和多参照的方式混合不同控制策略的想法。
In everyday life the brain must adapt to variable situations that may require a mixture of approaches including anticipatory synergy formation, through an internal body schema, and different control strategies. Unstable tasks are particularly challenging because deteriorate the predictive power of internal models and further enhance the instability potential of delayed sensory feedback. We explore this issue by means of three simulation studies: A) The hybrid control of a double inverted pendulum model, B) The bimanual stabilization of a saddle-like instability, C) Whole-body focal-postural dynamics. The simulation results support the idea that the brain can mix different control strategies in a task-oriented and multi-referential manner.
