Control method and apparatus for a moveable control member with n~3 observed states, the apparatus incorporating a sliding mode control system, operable to maintain the state point of the moveable member on a predetermined non-linear hyperplane having n-1 dimensions, the hyperplane being such that if the state point is maintained thereon, the maximum rate of change of the highest order observed state does not exceed that of which the control apparatus is capable, the sliding mode control system comprising digital processor means operable to reference n-1 low order observed states to the predetermined hyperplane to establish a desired value of the highest order observed state, the control system further comprising comparator means operable to compare said desired value with the observed highest order state, and means responsive to the comparator means and operable to implement the control action necessary to maintain the state point on the predetermined hyperplane.
