- Explain the idea and theory of space vector modulation and overmodulation . the implementation of svm and the realization scheme are given
详细介绍了系统的软硬件设计，给出了电路原理图和软件模块的设计原理和调用方法。 - This paper ? goal is to improve the performance of the electric vehicle ? drive system based on the existed schemes . limited by time , this paper focused on two research areas : ( 1 ) overmodulation scheme based on svpwm ( 2 ) speed sensorless control method
由于时间有限，本文所进行的研究工作主要集中在两个方面： （ 1 ） svpwm过调控制的研究（ 2 ）无速度传感器控制算法的研究。 - The theoretical analysis and result of simulation indicate that the two - phase modulation reduces the switching losses 50 % relative to the quasi - optimum and the space vector modulation and overmodulation can generate higher voltages with low total harmonic distortion
分析表明二相调制方法相对于准优化方法减少开关损耗近30 ，空间矢量的调制与过调制可以大大的提高直流母线电压的利用率。 - The simulation result indicates that the fuzzy controller makes the speed regulation system of shearer response quickly , small overmodulation , reliable performance and no dependence of model parameter , has strong robustness comparing to traditional controller
仿真结果表明：模糊控制器和传统控制器相比，可使采煤机调速系统响应快、超调小，性能稳定可靠，并对模型参数不依赖，具有较强的鲁棒性。 - For big hysteresis control , response time is long and overmodulation is big , but dynamic performance figure is not good when we only use pi controller 。 so , i try to design the whole control project which composed of the vapor wraps water level control system and combustion control system use the control equipment of double cross - parameter fuzzy - pi controller
单独采用pi控制,对大滞后控制,响应时间及超调很大,但动态性能指标差。因此,尝试采用双交叉参数fuzzy - pi控制器。组成了汽包水位和燃烧双交叉参数自调整fuzzy ? pi组合控制器的整体控制方案。
