Question 2: What is robust H-infinity control? H-infinity control question: Designing a desired controller so that the closed-loop system is stability and the transfer matrix satisfys that H-infinity control Designing K so that G is stability and the transfer matrix satisfys that introduction Question 1: What is H-2 control? H-infinity control question: Designing a desired controller so that the closed-loop system is stability and the transfer matrix can be minimized Fundamental knowledge Question: What is H-infinity norm? H-infinity tracking design of uncertain nonlinear SISO systems: adaptive fuzzy approach H-infinity tracking design of uncertain nonlinear SISO systems: adaptive fuzzy approach H-infinity tracking design of uncertain nonlinear SISO systems: adaptive fuzzy approach H-infinity tracking design of uncertain nonlinear SISO systems: adaptive fuzzy approach H-infinity tracking design in indirect adaptive fuzzy control The ideal control law: Due to the systems, f and g, is unknown, so the ideal controller is unavailable for the dynamic systems. The practical control law: H-infinity tracking design in indirect adaptive fuzzy control Finally, we have H-infinity tracking design in indirect adaptive fuzzy control Integrating above equation from t=0 to t=T yields: H-infinity tracking design in direct adaptive fuzzy control H-infinity tracking design in direct adaptive fuzzy control Robust Adaptive Neural Control for a Class ofPerturbed Strict Feedback Nonlinear Systems Robust Adaptive Neural Control for a Class ofPerturbed Strict Feedback Nonlinear Systems The coordinate transformation Robust Adaptive Neural Control for a Class ofPerturbed Strict Feedback Nonlinear Systems Backstepping design: step 1: Robust Adaptive Neural Control for a Class ofPerturbed Strict Feedback
