形态学计算可以粗略地定义为利用物理系统的形状、材料属性和物理动力学来提高计算效率。形态控制是形态计算在控制任务中的应用。在其理论部分，本文锐化和扩展这些定义，提出新的形式化的定义，并确定在哪些领域，我们提出的定义仍然是不够的。我们继续描述三个正在进行的研究，在这些研究中，我们将形态学控制应用于医学和化学问题。第一个涉及一个可充气的支持系统，用于运动受损的患者，并基于宏观物理和已经在机器人技术中测试过的概念。另外两个案例研究（化学微反应器的自组装;放射肿瘤学中诱导细胞修复的模型）描述了微米尺度上的过程和设备，其中底层物理系统的涌现动力学（例如，相变）由诸如扩散的随机过程支配。
Morphological computation can be loosely defined as the exploitation of the shape, material properties, and physical dynamics of a physical system to improve the efficiency of a computation. Morphological control is the application of morphological computing to a control task. In its theoretical part, this article sharpens and extends these definitions by suggesting new formalized definitions and identifying areas in which the definitions we propose are still inadequate. We go on to describe three ongoing studies, in which we are applying morphological control to problems in medicine and in chemistry. The first involves an inflatable support system for patients with impaired movement, and is based on macroscopic physics and concepts already tested in robotics. The two other case studies (self-assembly of chemical microreactors; models of induced cell repair in radio-oncology) describe processes and devices on the micrometer scale, in which the emergent dynamics of the underlying physical system (e.g., phase transitions) are dominated by stochastic processes such as diffusion.
