This paper investigates a fixed-time anti-unwinding attitude controller for spacecraft. With the use of rotation matrix, unwinding problem, which widely exists in controllers based on quaternion can be dealt with. By means of a fixed- time sliding mode surface, the desired attitude command can be tracked in a fixed time, the bound of which can be estimated without knowing any information of the initial values of system states. Mathematical demonstration and simulation results validate the effectiveness of the controller developed in this paper.

In this paper, we investigate the use of Kalman filter to enable robust tracking based on an efficient pose estimation algorithm, namely the four-point algorithm. Pose estimation is very useful in vision-based system control, for example in automatic driving and virtual reality inputs. Firstly, we have implemented a four-point pose estimation method with a personal computer. This estimation algorithm is supposed to be the method that requires the least number of point features for the generation of a unique solution. On the contrary, existing three-point algorithms may give multiple solutions. Then we have adopted a Kalman filter to enable robust tracking. Kalman filter is computationally efficient and very good at handling noise during tracking. The merge of these two techniques make us able to build a high-speed and yet robust system to be used in a wide variety of real applications. Furthermore, we have shown that a linear Kalman filter can be applied to filter off noises directly from the results of the four-point algorithm. Simulated and real data tests were performed and the results were satisfactory.

A nested Latin hypercube DOE (Design Of Experiment) involves at least a low accuracy experiments and a high accuracy one in Finite Element Method (FEM) Simulation. How to use the information contained in the regression model of previous low accuracy experiments in the design of high accuracy one needs deeply study because such information may be ignored in evenly sampling method, leading to a imprecise regression model of high accuracy experiment. This paper employ the gradient of the regression model of low accuracy experiments as the index of the information distribution of tested object to adjust the DOE of high accuracy one. Thus more information of object can be obtained in those high accuracy experiments and a more precise quadratic polynomials RSM (Response Surface Method) model is built.

The paper studies a problem of optimal control synthesis for curing the shell-like composite structure using open die molding in an autoclave. The necessary control should eliminate early hard skin formation, emergence of resin-rich or resin-dry areas, insufficient consolidation, and uneven cure. This purpose can be achieved through providing uniform distribution of temperature and degree of cure within the cured part volume. The used approach includes the joint CAD model of cured part and mould rectification to eliminate the topological errors, next import the repaired model to the finite element modeling system, where we formulate the transient cure process problem; its repeated simulation with varied durations of heating-up and isothermal holds to find their best values, which provide the acceptable objectives. The control synthesis problem is formulated as a multi-objective optimization problem where minimized objectives are deviations of temperature and degree of cure within a cured part considering constraints imposed by the properties of prepreg and manufacturing requirements. The Pareto-based optimization procedure allows estimating the best achievable quality indicators of cured composite parts, finding satisfactory control law, and decision-making.

Electric discharge machining (EDM) is the process of machining electrically conductive materials by utilizing exactly controlled sparks that happen between a cathode and a work piece within the presence of a dielectric liquid. This paper presents the design, manufacturing and working of an autonomous EDM which is compact, stable and safer in use. The actuators and power supply switching is controlled using an Arduino which makes decision based on inputs from five different sensors — fire sensor, lever sensor, temperature sensor, servo position sensor and limit switch. Constant monitoring is done through a graphical user interface built in Matlab.

We have performed frame modeling of knowledge — rules of explicit structures on the basis of explicit clustering, and for fuzzy structures, through implicit clustering. A set of modeling software has been developed for multi-criterion fuzzy management of selection according to various technical specifications: system performance, the number of computing modules, microprogram memory capacity, etc.

The article describes the thermogasdynamic model of small-scale gas turbine engine. This model takes the engine size into account during the efficiency assessment. The engine size is defined by the value of mass flow rate corrected by parameters at the exit of the compressor. The important features of working process of small-scale gas turbine engines are the increased hydraulic losses and decreased turbomachinery efficiency due to the increasing of a boundary layer relative thickness and relative tip clearances. This article describes the mathematical models that provide the corrected values of turbomachinery and combustion chamber efficiency ratios. This approach provides more adequate results of working process parameters optimization and may be used for conceptual designing of micro gas turbine engines.

In ground-to-ground military engagements, launchers used in land vehicles play an important role for armies. In application, orienting missiles and rockets which are fired from the land vehicles and finally hitting the intended targets with high accuracy are issues that should be taken into consideration. In order to attain this goal, it is vital that an effective control algorithm be designed. As proven several times, the most robust and reliable control systems can be designed in a model-based manner. When the launchers are allocated on the moving vehicles, their control, diminishing the thrust effect during the munition firing and preparing the system for a new shot within a short duration get more important. In this study, the differential equations of motion of an electromechanically-actuated launcher are presented regarding its motion in both azimuth and elevation axes and a two-loop cascaded control system is proposed. As the inner loop of this scheme is enrolled to provide the stabilization by taking the angular speed variables of the launcher in both azimuth and in elevation planes as control variables, its outer loop is designated to make the angular position control of the launcher.
