How cooperation emerges and is stabilized has been a puzzling problem to biologists and sociologists since Darwin. One of the possible answers to this problem lies in the mobility patterns. These mobility patterns in previous works are either random-like or driven by payoff-related properties such as fitness, aspiration, or expectation. Here we address(More)
This paper presents design, analysis, and experiment of the feed cable-suspended structure for the next generation large spherical radio telescope. To begin with, considering the requirement of the orientation of the feed cable-suspended structure increased to 60deg from 40deg, optimization design of the structure is performed. Then, aiming at the drawback(More)
As is well known, a wire-driven parallel manipulator is a manipulator whose end-effector is driven by a number of cables instead of rigid links. It shows several promising advantages over its rigid-link counterpart, such as simple light-weight mechanical structure, low moment inertia, large reachable workspace and high-speed motion. In the 1980s, the(More)
This paper addresses the cable tension distributions of a cable-driven parallel robot with non-negligible cable mass for large dimension mechanisms. A well-known model which describes the profile of a cable under the action of its own weight allows us to take the cable sags into account. In addition, an approach to computing the cable tensions is presented,(More)
Output prediction is one of the difficult issues in production management. To overcome this difficulty, a dynamic-improved multiple linear regression model based on parameter evaluation using discrete Hopfield neural networks (DHNN) is presented. First, a traditional multiple linear regression model is established; this model takes the factors in production(More)
In order to achieve the high motion precision of the macro-micro parallel manipulator system for a radio telescope, a decoupled tracking and prediction algorithm based on principles of parallel mechanisms is presented. Then the adaptive interaction PID controller, which utilizes the adaptive interaction algorithm to tune the parameters of a canonical PID(More)
