This is the demo file for L1 adaptive controller with unknown parameter, unknown disturbance, unknown control effectiveness: dot x(t) = Ax(t) + b(omega u(t) + heta(t)^ op x(t) + sigma(t)) DoSims.m: This script initializes the model parameters, run the simulation. You can split the parts you need and do the simulations according to your interest. L1Model_sec2.mdl:the implementation of the system. Refer to the following paper for background: C. Cao, and N. Hovakimyan, “L1 adaptive controller for systems with unknown time-varying parameters and disturbances in the presence of non-zero trajectory initialization error”, International Journal of Control, Vol. 81, No. 7, 1147–1161, July 2008
