Sliding-mode control method was adopted incorporating adjacent cross-coupling control structure in the proposed control strategy based on 4-order field-oriented ind.

In this paper ,the result of numerical imitate of the phase -locked loops with closed amplitude control(A -CCPLL)was obtained ,and its ability of solving modulation was explored.

The internal error is deal with cross-coupling controller,the external error is eliminated by a expert-fuzzy controller.

Based on the Single Channel Monopulse self-tracking system,this paper analyses the reasons of cross-coupling,and discusses all factors and solutions of the cross-coupling deterioration.

Two models for analyzing both the cross-couplings and their phase relationships and the implementation in cavity-filters by establishing auxiliary signal passages and adding control parts between non-adjacent resonators to both introduce finite transmission zeroes and optimize the performance of filters are proposed.

Comparison of UPFC performance betweencross coupling and decoupling controls;

Stepped Impedance Resonators(SIR) taken as basic resonator unit of coaxial filters,a kind of generalized Chebyshev coaxial-cavity filter through cross coupling is designed.

For having missile of two sets of the same side directions autopilot,there is cross coupling between two control channels.

Design of combline SIR cross-coupled coaxial-cavity filter;

In this dissertation, the design of dual-frequency filters has been intensively investigated based on studies on the synthesis theory of cross-coupled filters and the parasitic passband characteristic of resonators.

A synchronized cross-coupled controller for base joint of dexterous robot hand was designed,including feedforwards of velocity and acceleration,feedbacks of synchronous errors and position errors,and a smooth robust nonlinear feedback compensator.
