This paper describes a single-phase full-bridge inverter that possesses limited current ripple at the dc link while providing a sinusoidal square power at the ac output. This is achieved through the addition of an extra pair of switches and complementary control for the full-bridge inverter. The extra switches operate to prevent the double-line frequency ripple current from flowing into the input...
A Vision measurement system is constructed for the Seal Packing collar, and the mathematical morphology is used in Edge Detecting process because of the image which obtained through the Telecentric lens in the system has a clear feature of bimodal. Then the algorithm for Edge Detecting and system calibration has no more complex structure based on the Binary image characteristic, furthermore, the feature...
Finite positions method is presented in this paper for complete balancing of shaking forces for planar and spatial mechanisms as well as the solutions to its equations. By using the method, only correctly formulated single-linked-chains (SOC) with proper connection and leaf components are needed to substitute into the equations to solve the parameters, which will be used to fully balance the shaking...
After analyzing the shortcomings of traditional code-centric development process for embedded computer numeric control (CNC), this paper presents a new approach: Embedded cNc Development based on modEl Driven (ENDED) which enjoys the advantages of model-driven development (MDD) and domain specific modeling (DSM). This approach is a model-based methodology which includes three parts: construction of...
