The adaptive control scheme is considered as one of the methods against the uncertainties and to improve the robustness of the control system. With this in mind, the adaptive control of nonlinear systems has attracted a great deal of attention, and many sort of adaptive strategies for nonlinear systems were proposed in the early 90's. Most of them, unfortunately, are based on the state feedback strategy ; in these methods, one has to introduce a state observer if the state variables are not available. Therefore the controller structure becomes complex and this might be a restriction for the application of these adaptive methods to practical systems. Thus it is very important from the point of practical application to consider a controller with simple controller structure and robustness with respect to uncertainties. This research was concerned with the synthesis of design scheme of such simple adaptive controls based on output feedback for nonlinear systems including MIMO systems, where only the output signal is available. In particular, the following topics were studied.1)Design of output feedback based robust adaptive control systems for MIMO nonlinear systems.2)Basic studies on the design schemes of control systems with a parallel feedforward compensator.3)Adaptive output feedback control design for discrete systems4)Experimental validation of proposed methods

自适应控制方案被认为是对抗不确定性并提高控制系统鲁棒性的方法之一。鉴于此，非线性系统的自适应控制引起了人们的广泛关注，并在20世纪90年代初提出了多种非线性系统的自适应策略。不幸的是，其中大多数都是基于国家反馈策略；在这些方法中，如果状态变量不可用，则必须引入状态观察器。因此控制器结构变得复杂，这可能限制这些自适应方法在实际系统中的应用。因此，从实际应用的角度来看，考虑控制器结构简单且对不确定性具有鲁棒性的控制器非常重要。本研究涉及基于非线性系统（包括仅输出信号可用的 MIMO 系统）的输出反馈的此类简单自适应控制的设计方案的综合。具体研究了以下课题：1）基于输出反馈的MIMO非线性系统鲁棒自适应控制系统设计。2）并行前馈补偿器控制系统设计方案的基础研究。3）自适应输出反馈控制设计离散系统4）所提出方法的实验验证
