Abstract
This paper offers an approximate algorythm of multiple-input, multiple-output adaptive high speed model following system by the application of a special form of so-called high feedback gain method in the frequency domain. By this scheme, the initial following errors will decrease very rapidly, and there remain some small residual errors. This residual errors converge assymptotically if the system inputs are step inputs and if the system satisfies some conditions, and don't converge for other cases. To apply this method we need some a priori information of the plant, but the estimation errors of plant parameters are allowed to be considerably large. This system has an adaptive or so-called robust character by the application of high feedback gain method. But the construction of this system is different from the so-called model reference adaptive control system (MRACS), because the construction of this system is linear, and the MRACS usually contains some nonlinear parts. The numerical simulations of this scheme show very good results.
