The design of model reference adaptive control

The adaptive control technique based on the Lyapunov stability theorem is used widely, which is the model reference adaptive control (MRAC). Based on the MRAC method, an adaptive feed-forward controller was designed to decrease the error. The simulation was made by Matlab. The simulation result shows that it can achieve good control effect even if the parameter of controlled objects changed in large scale. When controlled objects changes from linear time-invariant system into nonlinear time-variant system, it can still obtain better control effect.
