An adaptive steady predictive functional control algorithm using the orthogonal Kautz function base has been designed in this paper. Performance of the closed-loop system is discussed, and the stability condition is given based on Lyapunov stability theory. A new improved parameter compensating algorithm depended on genetic algorithm is introduced. The simulations verified the given strategy.
A novel robust Hinfin decentralized intelligent control (RHDIC) strategy is proposed for the trajectory following problem of robot manipulators. The proposed system is comprised of a computed torque controller and neural robust controller with new learning algorithm. Based on Lyapunov stability theorem, it is shown that the proposed controller can guarantee stability of closed-loop systems and satisfactory...
This paper investigates the aggregation of dynamical agents in network. The communication topology of network is characterized by a undirect graph and the agents are Lyapunov stable distributed in a plane. We provide with the conditions under which the group of agents will achieves gradually aggregation. Numerical simulations show that our theoretical results are effective. By comparison with the...
The global asymptotically stability of FAST TCP by nonlinear delay differential equation with heterogeneous delays is developed. Since the traditional self-stabilization approaches lack the flexibility to deal with the variable adaptation of the complex network within FAST TCP, the study emphasizes an alternate self-stability analysis approach, namely Lyapunovpsilas second method. The time-delay that...
Theorem of alternatives based on the separation theorems are proposed to provide systematic and unified proofs of necessary and sufficient conditions for solvability of Lyapunov inequality on P. As an application of the theorem of alternatives, we investigate the conditions for the existence of feasible solutions to Lyapunov inequality on P and obtain a restatement of the celebrated Lyapunov stability...
Control of pneumatic servo systems is well-known to be challenge due to highly nonlinearities in the actuator dynamics and compressibility of the media. Most state feedback based strategies for the pneumatic servo systems require full state feedback to stabilize the closed loop system which implies the need for pressure measurements of the cylinder. Many researchers used state observers to complete...
An extended proportional navigation guidance (EPNG) law based on Lyapunov stability is proposed applying the concept of virtual target and 3-dimensional pursuit-evasion model. This guidance law can satisfy the requirements of miss distance and terminal angle, thus it guarantees that different parts of the large-airspace varying trajectory link smoothly. Guided by this guidance law an anti-warship...
