Progress in aircraft designs heavily depend on automatic flight control system. Modern aircraft have a wide flight envelope (linear and nonlinear) region. This study considers the design of stability and control augmentation system (SCAS) in high angle of attack region for a modern type aircraft via back stepping method. Because of highly nonlinear phenomena in aerodynamic parameters, a locally...

[Purpose] The purpose of this study was to determine the effect of stepping limb and step direction on step distance and the association of step distance and stepping laterality in step difference with walking ability and motor dysfunction. [Subjects and Methods] The subjects were thirty-nine patients with chronic hemiparesis as a result of stroke, who performed the MSL (Maximum Step Length) te...

Latex dipping machine is based on a latex patent products new-production condom and the development of the machine. The latex dipping agencies combined with production condom mechanism. First it realized a 3-dimensional accurate localization system using stepping motors. SIMATIC S7-200 series programmable controller, motion module EM253 and stepping motor are tied in wedlock to realize allocati...

Purpose Generally, humanoid robots usually suffer significant impact force when walking or running in a non-predefined environment that could easily damage the actuators due to high stiffness. In recent years, utilization of passive compliant series elastic (SEA) for driving humanoid's joints has proved capability many aspects so far. However, despite being widely applied biped robot research f...

To begin, we consider a basic example of a discrete first passage process. Consider an unbiased Bernoulli walk on the integers starting at the origin. We wish to determine the probability, R, that the walker eventually returns to 0, regardless of the number of steps it takes. Without loss of generality, say the walker’s first step is to 1. From here, the walker can either step left to 0 or can ...

input frequency is one of the important variables in design and performance analysis of single-sided linear induction motors (slims). changing the frequency changes both the dimension of the slim in design process and the performance of the designed motor. the frequency influences the induced eddy currents in the secondary sheet as well as saturation level of the secondary back-iron. in this pa...

The thin-disc piezoceramic-driving ultrasonic actuator dedicated to a stepping ultrasonic motor is proposed. The mechanical hysteresis and dead-zone phenomena are automatically compensated by a closed loop servo control, i.e. Fuzzy Sliding-Mode Control (FSMC), for position tracking. The controller design of FSMC has syncretized the fuzzy reasoning and sliding mode control with robust stability ...
