Low-Cost Embedded controller for complex control Systems

Journal of Electronic Science and Technology 2013年第1期11卷 89-95页

Because of limited resource of embedded platforms, the computational complexity of advanced control algorithms raises significant challenges for the use of embedded systems in complex control field. A Scilab/Scicos based embedded controller is developed on which various control software can be easily modeled, simulated, implemented, and evaluated to meet the ever-expanding requirements of industrial control applications. Built on the Cirrus Logic EP9315 ARM systems-on-chip board, this embedded controller is possible to develop complex embedded control systems that employ advanced control strategies in a rapid and cost-efficient fashion. Due to the free and open source nature of the software packages used, the cost of the embedded controller is minimized.

＜正＞Besides characteristic harmonics,there are many non-characteristic harmonics in power *** common passive filter cannot deal with it,which worsens performance and may be results in the resonance to destroy the filter *** to this problem,the paper presents a novel shunt hybrid active power filter（PHAPF）,the principle of PHAPF is analyzed and a complex control strategy for detecting both load harmonics and grid harmonics is proposed. Simulative results show that the PHAPF has excellent performance and application outlook.

In view of the mars reentry problem under external disturbance,this paper presents a guidance algorithm based on drag *** of all,the reference drag is calculated based on the reentry model and the reference ***,estimated disturbance via the sliding mode observer,this paper improve the accuracy of the controller parameters and increase the anti-disturbance ***,the sliding mode guidance law for drag tracking is proposed based on the observer,reentry model and the reference *** simulation results indicate that the anti-disturbance capability of the guidance law is increased by introducing the sliding mode *** proposed guidance law can effectively enhance the response speed and decrease the tracking errors,with higher practical value,compared with the traditional PD algorithm.
