The principles and structure of a new economical pulse-type servo drive system were presented. One part is main control board for servo motor with incremental encoder, which receive pulse position command form upper controller. With the scholastic calculation in main control part of servo drive, and the dead time of PWM signals was compensated by hardware circuit, this drive system has a high performance...
This paper presents a fuzzy modeling with immune algorithm to search for the optimal solution in conceptual design of mechanisms. First, a new problem formulation model that involves fuzzy logic to reflect the imprecise nature of objectives is presented. Then, an immune optimization algorithm (IOA) is used as a key technology to find the optimal solution in many combinatorial solutions, which can...
Computer aided instruction (CAI) technology has been proved that it can strongly support teaching in improving class quality, students' studying efficiency and effectiveness. In terms of the requirement of general vehicle design course, this paper proposes a way to this kinds of course teaching by offering a practical teaching tool, which is based on supporting multi-engineering modeling and simulation...
