The problem of trajectory sensitivity considered in the literature was restricted to the continuous-time systems. Some of the criteria provided in previous work (9, 10) are extended to the discrete-time control systems. Two methods based on the Z-domain design technique are developed to overcome the difficulty of obtaining the variations of control due to the changes of system parameters. The obtained Z-domain controllers are particularly suitable for implementation on a microprocessor or digital computer. mm m (9 .10)
