Research Abstract

The approach for linearized compensated adaptive control of nonlinear systems which has many effective merits such as robastness, stability and accuracy for control is proposed. First, nonlinear system are identified by a second order differential equation with coefficents described second order polynomial. In the case of higher than the second order system, The system can be approcimated by the above nonlinear second order system plus an appropriated linear system. In these system, We can control by using usual linear controller for large range of operationg point on the nonlinear system. However for the large abrupt change of system's parameters, adaptation algonithms sometimes can not work well. In order to improve this defect we choose the linearized stable model before hand for the large amount of parameter changes of nonlinear systems. It is found that the approach can be effective to decrease modelling error by simulating results.
We consider some feed water heating system of a power plant as a practicul application. Its equivalent heat capacity is the most important parameter, it is identified online, then linearized model is constracted.
We use the M-sequence as the test signal for identifing nonlinear system whose amplitude is randomly changed. This signal is quite effective for the system having strong nonlinearity.
