The paper proposes a system control composed of harmonic detection and current control for hybrid active power filter (HAPF). Method of harmonic detection is presented to get the superior harmonic reference signal for improving compensation performance of HAPF system. Detection method is based on self-adaptive noise countervailing principle. An algorithm of normalized LMS (Least Mean Square) with...
Among numerous control schemes for flexible joint robots, the main problem is that the full state variable of acceleration and jerk must be known, which are difficult to measure, and the noise may be merged in the main signal. To solve this problem, a self adaptive composite control scheme is developed to control the flexible joint robots with modeling errors and subject to uncertain disturbances,...
According to the positioning accuracy requirements of the two-dimensional precision positioning system with high speed, wide platform, large range and linear motor driving, an intelligent positioning control system based on the linear motor is studied in this paper. The precision positioning experiment is also conducted. The experimental result shows that the positioning accuracy and the dynamic performance...
Mathematical model of exhaust temperature control in micro gas turbine is introduced. To obtain better performance, a self-adaptive PID control is applied to the exhaust temperature control. The parameters of PID control are tuned by radial basis function (RBF) neural network. In this paper, the RBF neural network is given which has been used extensively in the areas of pattern recognition, systems...
This paper proposes a cerebellar model articulation controller(CMAC) used in liquid-level control system. CMAC is thought as a kind of association memory neural network. It can be used to approach any nonlinear function, dynamical modelling, etc. In this paper neural network was used on-line to identify the controlled plant and the weights of the adaptive PID controller are adjusted timely based-on...
