Linear feedback control systems (LFCS) are amenable to numerous object recognition and detection tasks on account of its functional properties in signal filtering and error correction. In fact, there exists an intimate relationship between control states and salient values. Therefore, we propose a novel semi-supervised classifier which makes use of linear feedback control theory to improve saliency...
PMSM vector control system with a proportional-integral (PI) controller exists some defects such as slow speed response, large torque ripple and poor anti interference ability. A new fuzzy PI control method with adjustable proportion factor (APFPI) is proposed in this paper. The proportion factor can be adjusted by RBF neural network (RBFNN) online. In the PMSM vector control system, the current loop...
In order to improve the accuracy of electro-optical tracking system, a novel feed forward-IMC controller based on Internal Model Control has been designed and made the simulation on the system. The simulation result showed that the feed forward-IMC controller can meet the need of high accuracy of electro-optical tracking system and it also have good feasibility and robustness. It has the better tracking...
Based on research of the phase plane division control method, according to the structure of wheel loader steer by wire system and its work condition, the fuzzy five states control system specially designed for wheel loader steer by wire system is introduced in this paper. To verify its performance, the controller was simulated in MATLAB/SIMULINK based on the model of wheel loader steer by wire system...
Electro-optical tracking devices in the television or infrared automatic tracking system, miss distance lag system overshoot increased, lengthened the transitional period, affecting the stability control system and reduce the tracking precision. Feedforward control technology is to improve the tracking accuracy and to maintain the stability of the system an effective way. The speed of introduction...
Based on research on the algorithm and control strategies of automatic transmission in wheel loader, the electronic control system adopted embedded technology for model A306 transmission is introduced in this paper. The embedded chip ATmega128 with RISC is used as CPU in the design. The hardware of the intelligent control system is satisfied with the requirements of gear shift. With the modular structure,...
The stabilized soil is an important material used widely in road construction. The mixture ratio is an important factor impact on its quality directly, even influences the quality of highway construction. The electronic belt scale is used to weight and control the material flow by adjusting the motor speed of belt conveyor to control the mixture ratio of the stabilized soil. In this paper, the fuzzy...
