This paper develops a new adaptive multiple-model control scheme for a class of nonlinear multiple-input multipleoutput(MIMO) dynamic systems to compensate uncertain actuator failures using an error transformation. Such an adaptive control scheme, consisting of multiple estimators, controllers and a control switching mechanism with multiple cost functions,can ensure desired system stability and asymptotic tracking properties, despite the presence of failure uncertainties. Simulation results of an application to a spacecraft model verify the effectiveness of the proposed multiple-model based adaptive control scheme.

The increasing integration degree of circuits in electronic systems makes faults detection and isolation more and more difficult. Design for testability(DFT) was applied to solve the problem. In this procedure, designers are required to set an optimum arrangement of sensors to achieve the best testability. But the search of the best test points combination is usually conducted by manual work. To simplify this blind and inefficient procedure, a test point optimization algorithm based on multi-signal flow model is proposed in this paper and is successfully applied in a CMG. First, the basic conception of modeling is introduced and the analysis of testability is converted to the calculation based on dependency matrix. Then the test points optimization problem is described and analyzed by an improved genetic algorithm. At last, the algorithm is examined by the CMG's A/D board subsystem. The result shows the algorithm can find the best solution with excellent efficiency.

The smart beam is widely used as a means of studying the dynamics and active vibration suppression possibilities in aircraft wings. The advantages obtained through this approach are numerous, among them being aircraft stability and manoeuvrability, turbulence immunity, passenger safety and reduced fatigue damage. The paper presents the tuning of two controllers: Linear Quadratic Regulator and Fractional Order Proportional Derivative controller. The active vibration control methods were tested on a smart beam, vibrations being mitigated through piezoelectric patches. The obtained experimental results are compared in terms of settling time and control effort, experimentally proving that both types of controllers can be successfully used to reduce oscillations. The analysis in this paper provides for a necessary premise regarding the tuning of a fractional order enhanced Linear Quadratic Regulator, by combining the advantages of both control strategies.
