| Summary: | A design methodology is developed for obtaining tracking any combination of exponential, polynomial and sinusoidal are developed which guarantee robust tracking for uncertain because it clearly shows the effect of the non-minimum phase centers around a solution for the error equation E(s) = [1 - complicates the design process because the perfect-tracking controller which will make [1 - H(s)] orthogonal to Yd(S). controllers for non-minimum phase systems. The discussion demonstrated for systems that do not have plant uncertainty. Examples are given which show that non-minimum phase systems Examples are provided to show how to select a feedforward feedback controller. QFT is used as the robust design tool feedforward controller only provides perfect tracking for the Feedforward controllers can be selected to perfectly track H(s)] Yd(S)'Tracking error is eliminated by making [1 - H(s)] have inherent performance limitations which are compounded input signals. The introduction of plant uncertainty nominal system. In the presence of plant uncertainty, robust only provided by the feedback controller. Magnitude bounds orthogonal to Yd(S)- Perfect tracking is achieved and stability. These bounds are used as guides for designing a systems. Phase bounds are also developed which insure robust tracking performance is determined by sensitivity reduction when uncertainty is introduced. zeros and plant uncertainty on robust tracking performance. |
