To counter BTT guidance mode, new relative motion equations of the targetaircraft and the attack aircraft are proposed. The inverse system theory of the nonlinearcontrol is used, and the direct BTT-180 guidance command is solved, which can operatethe attack aircraft to automatically complete the flight mission of the preceding stage ofthe terminal weapon delivery, and thus the automatic attack is extended from the stage ofthe terminal weapon delivery to the preceding stage of the terminal weapon delivery.

A multivariable inverse nonlinear control scheme is developed to decouple the strongly nonlinear double extraction steam turbo unit, improving the transient stability of the power and heating system. Computer simulation tests show that not only does the control scheme achieve satisfactory decoupling of the high and low pressure turbines and the electric power, remarkably improving the transient stability, but also the design is very intuitive and concise. 

In this paper, a weighted least square support vector machine algorithm for identification is proposed based on the T-S model. The method adopts fuzzy c-means clustering to identify the structure. Based on clustering, the original input/output space is divided into several subspaces and submodels are identified by least square support vector machine （LS-SVM）. Then, a regression model is constructed by combining these submodels with a weighted mechanism. Furthermore we adopt the method to identify a class of inverse systems with immeasurable state variables. In the process of identification, an allied inverse system is constructed to obtain enough information for modeling. Simulation experiments show that the proposed method can identify the nonlinear allied inverse system effectively and provides satisfactory accuracy and good generalization.

Static synchronous compensator（STATCOM） is mainly applied to the reactive power compensation condition. This paper established the model of indirect current control. Indirect current control is a kind control strategy of phase and amplitude. The model characteristic is of nonlinear and strong coupling. The nonlinear decoupling characteristics of inverse system combine with the characteristics of nonlinear neural network, so, this paper proposes a control strategy based on the structure of neural network and inverse system. This paper established a simulation model in MATLAB. The simulation results show that control strategy of reactive power compensation has good dynamic performance. This control strategy plays a guiding role for the design of the reactive power compensation equipment.

A new algorithm for constructing an inverse of a multivariable linear system is presented. This algorithm makes the constructing an inverse of the higher order matrices into searching for the equivalent normal form of the lower order matrices. Consequently, the calculation is more simple efficient and programmed than previous methods. Another result of the paper is that the lower reduced inverse system is obtained, by selecting special bases of the observable space of the original systems, it reveals the effect of the observability of the original systems on the order of the inverse systems.

The signal will encounter refraction,changing in speed and get attenuated as passing through the wall in the through-the-wall radar. In this paper,by analyzing the echo signal model,the relationship among the transmit signal,target position function and the wall system function in view of the system concept will be achieved,a new wall compensation algorithm based on the inverse system and a method of estimating the wall system function using the real data will be proposed. Proof of concept is provided using real data collected in a laboratory environment. The results show that the new wall compensation algorithm can eliminate the effects of unknown wall parameters very well.

A novel control method for the nonlinear and complex plants with environmental uncertainties and variable parameters has been proposed by use of the nearest neighborhood clustering algorithm, the fuzzy control and the variable regressive estimation (VRE) technology. It overcomes the defects of the other adaptive methods such as the strong dependence to the system and the difficulty of the acquirement of the professional knowledge during the modifying period of the rules. The application of new algorithm to the electrical heating furnace with multiple zones demonstrates the advantages of the proposed method.
