Input and state delay problem will cause instability to system. This thesis takes advantage of state transformation method to eliminate the input delay. The transformed system is free to the input delay phenomenon. The Adaptive technique is utilized to estimate the perturbation of system in order to minimize the control input consumption and make the error minimize. We also propose (1) Sliding Mode Controller (2) Integral Sliding Mode Controller to overcome the problem of state delay and perturbation and make system reach to sliding surface and asymptotically stable.
Finally, we utilize the simulations of two examples to compare the advantage and shortcoming of (1) Sliding Mode Controller (2) Integral Sliding Mode Controller, it can be verified the validness of the controllers proposed in this thesis.
