According to the design complexity due to the diversification of ship motion simulator structure and control system, we put forward that combining Stewart parallel structure based on modular design with open control system based on EMC2 controller. The system utilizes PC based on the hardware structure such as motion control interface card, servo electric cylinder and software structure such as real-time operation system UBUNTU and professional control software EMC2 which can ensure the system’s being real-time. We have studied the movement law of ship in waves and obtained the ship movement sample changing with time in waves. And we do the ship motion simulation well with the motion simulator system.

PLC dynamically adjusts power voltage by controlling switches of transformers with different combinations, which is based on the theory of 8421, and makes voltage changes in a very small range. By using this system, energy is saved, and the damage of illumination equipment from voltage instability is greatly reduced, and the life of lamps is effectively extended. Meanwhile, by using the touch screen, this system not only can realize the real time parameter display, but also achieve the real time operation on the panel.

This paper researches on the control system for wind power generation of DFIG (Doubly Fed Induction Generator). DSP TMS320F28335 was used as the core CPU of the control system, which can meet the requirement of high precision and real time. An embedded real-time operation system (RTOS) was transplanted into TMS320F28335 and some function blocks in common use were added into the RTOS. The human-machine interface of the control system was programmed with LabVIEW, which perform the control function and can process the data came from the control system. By using this control system, many control arithmetic of wind power generation of DFIG can be tested in the laboratory.

Microwave ablation is widely recognized as a promising minimally invasive tool for treating cancer. Real-time monitoring of the dimensions of the ablation zone is indispensable for ensuring an effective and safe treatment. In this paper, we propose a microwave imaging algorithm for monitoring the evolution of the ablation zone. Our proposed algorithm determines the boundary of the ablation zone by exploiting the time difference of arrival (TDOA) between signals received before and during the ablation at external antennas surrounding the tissue, using the interstitial ablation antenna as the transmitter. A significant advantage of this method is that it requires few assumptions about the dielectric properties of the propagation media. Also the simplicity of the signal processing, wherein the TDOA is determined from a cross-correlation calculation, allows real-time monitoring and provides robust performance in the presence of noise. We investigate the performance of this approach for the application of breast tumor ablation. We use simulated array measurements obtained from finite-difference time-domain simulations of magnetic resonance imaging-derived numerical breast phantoms. The results demonstrate that our proposed method offers the potential to achieve millimeter-order accuracy and real-time operation in estimating the boundary of the ablation zone in heterogeneous and dispersive breast tissue.
