| 1 | 网络化控制系统中采样周期的优化求取显示文摘针对存在时延的网络化控制系统,建立系统的增广状态空间描述,并且根据时滞相关稳定性判据,求取保证系统渐近稳定的最大允许时延.其次,根据建立的增广状态空间描述模型给出以优化控制性能为目标的优化函数,在假设系统时延为最大允许时延的情况下,通过求解性能优化函数极小值得到采样周期的优化解.最后,引用实例验证所提方法的可行性. | 王志文 高红红 王沛禄 | 2015 | 兰州理工大学学报2015，41，3： | 2 |
| 2 | SCHMM-based Compensation for the Random Delays in Networked Control Systems显示文摘In order to compensate the network-induced random delays in networked control systems(NCSs), the semi-continuous hidden Markov model(SCHMM) is introduced in this paper to model the controller-to-actuator(CA) delay in the forward network channel. The expectation maximization algorithm is used to obtain the optimal estimation of the model s parameters, and the Viterbi algorithm is used to predict the CA delay in the current sampling period. Thus, the predicted CA delay and the measured sensor-tocontroller(SC) delay in the current sampling period are used to design an optimal controller. Under this controller, the exponentially mean square stability of the NCS is guaranteed, and the SC and CA delays are compensated. Finally, the effectiveness of the method proposed in this paper is demonstrated by a simulation example. Moreover, a comparative example is also given to illustrate the superiority of the SCHMM-based optimal controller over the discrete hidden Markov model(DHMM)-based optimal controller. | Yuan Ge Yaoyiran Li | 2016 | International Journal of Automation and computing2016，13，6： | 0 |
