我们提出了一种混合模型预测控制算法,共识互补控制(C3),系统,使和打破接触他们的环境。许多国家的最先进的控制器的任务,需要启动与环境的接触,如运动和操纵,需要一个先验模式的时间表,或者是如此复杂的计算,他们不能运行在实时速率。我们提出了一种方法,基于交替方向的乘法器(ADMM),能够高速推理的潜在接触事件。通过共识制定,我们的方法使并行化的接触调度问题。我们验证了我们的结果的三个数值例子,包括两个摩擦接触问题,和物理实验上的欠驱动多接触系统。
We propose a hybrid model predictive control algorithm, consensus complementarity control (C3), for systems that make and break contact with their environment. Many state-of-the-art controllers for tasks which require initiating contact with the environment, such as locomotion and manipulation, require a priori mode schedules or are so computationally complex that they cannot run at real-time rates. We present a method, based on the alternating direction method of multipliers (ADMM), capable of high-speed reasoning over potential contact events. Via a consensus formulation, our approach enables parallelization of the contact scheduling problem. We validate our results on three numerical examples, including two frictional contact problems, and physical experimentation on an underactuated multi-contact system.
