Abstract
When disturbance or influence of uncertainty can be measured, its influence on the system performance could be largely attenuated by the use of a feedforward strategy. However, in many practical applications, it is difficult to directly measure disturbance such as external load so this feedforward strategy cannot be directly realised. Disturbance observation and estimation techniques provide an alternative approach to realise feedforward strategies in these applications. This talk outlines the development of the disturbance observer-based control techniques (DOBC) particularly for nonlinear systems using a state space representation. Compensation design for disturbance entering systems in the same or different channels of control inputs (so called matched or unmatched disturbance) is discussed. Recent development of DOBC including robust control design and input-output realization is also presented.
