The vibration suppressive control problem is a challenge of flexible-joint space manipulators, which is settled by solving the energy optimal nonlinear control problem in this paper. Based on Legendre pseudo-spectrum method, the nonlinear model of optimal control problem is converted into the corresponding nonlinear programming problem. The complex and difficult two-point boundary value problem is solved by SNOPT. Compared with the traditional controller, the simulation results show that the joint trajectory can obey the joint flexible factors to move from the initial state to the end smoothly with a better result of vibration suppression in the process of movement by using the LPM. It can also ensure the terminal control precision.

In practice, multi-skilled labor is widely used. There are constraints of available and unavailable time on those resources, and each resource possesses multiple different skills. For the resource attributes of multiple skills and time windows, it's extremely challenging to arrange the activities and allocate resources in project scheduling. Aimed at this kind of problems, a mathematic programming model is developed and a Rollout Algorithm based on priority rules is proposed. In order to allocate resources quickly, a heuristic method for resource allocation is embedded in the algorithm. The results of some numerical experiments indicate that the performance of the proposed algorithm could obtain the satisfactory solution of the problem and be suitable for solving the problems of large scale. It is verified that the algorithm is effective.

This work investigates the consensus problem of a group of nonlinear agents over a fast-switching network. The communications between agents are bidirectional and time delay exists. The topology, which specifies the communications, is assumed to be switched within a finite set of topologies, reflecting a practical fast-varying network environment. Based on the Lyapunov functional stability theory and the averaging technique, a relation between the consensus condition for the time-averaged network and the studied network is established. It reveals that, when the switching frequency is high enough, the consensus of the time-averaged network induces the consensus of its counterpart. This result has been verified and illustrated by numerical simulations. It is also interesting to note that consensus is possible even when all networks are disconnected.

A novel scheme for object localization and tracking under family environment is presented based on fusion of multiple sensors, which include two laser sensors and camera sensors. The two laser sensors and two cameras are used to locate the object separately, and multiple sensors probability data association fusion algorithm is used to track the objects. Firstly, object detection is realized by laser sensors and vision sensors separately. Secondly, the laser data is fused by Extended Kalman Filter. To obtain the vision location results, background model is built by adaptive background updating based on motion history images. Background subtraction is used to acquire the original location result, which is filtered by Kalman Filter. Finally, multiple sensors probability data association fusion algorithm is used to fuse the different kinds of data. Experimental results show that the scheme can efficiently solve the problem of object localization and tracking.

The paper describes a new ultrasonic measurement technology that evaluates a spray nozzle cooling characteristics based on measured time-of-flight data using an electromagnetic ultrasonic transducer (EMAT). A spiral electromagnetism ultrasonic transducer was used to measure the ultrasonic velocity dependence of temperature in a certain thickness metal plate. The instantaneous time-of-flight time data were used to determine the velocity and deduce the interior and surface temperature. To verify the validity of the ultrasonic measurement result, one-dimensional unsteady heat transmission equation is established to compute the heat transfer coefficients (HTC) theoretically compared with ultrasonic measurement results. Through some one-dimensional analysis, this work will show that the HTC is a natural and stable quantity to estimate ultrasonic time of flight measurements.

This study proposes a high precision selective harmonic compensation scheme for active power filters, which designed by using the basic theory of GPC. A generalized predictive control (GPC) strategy based on the transfer function model is adopted. The GPC can compensate the delay in detecting the harmonic and the better result of compensation for harmonic can be achieved. As Kalman filter can detect each order harmonic separately, the compensation on delay time arouse from digital implementation is performed. The proposed scheme improves the stability of APF, prompts the precision of harmonic compensation and is applicable to both single phase and three phase inverters. The effectiveness of the scheme is verified by simulation. The experimental results show that compared with traditional controller, the GPC controller can improve the accuracy and robustness of the system and the feasibility of GPC in the program can be proved.
