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反对不确定性的方法之一，并改善了控制系统的鲁棒性。考虑到这一点，非线性系统的自适应控制引起了很多关注，并在90年代初提出了许多非线性系统的自适应策略。不幸的是，其中大多数是基于州反馈策略的；在这些方法中，如果状态变量不可用，则必须引入状态观察者。因此，控制器结构变得复杂，这可能是将这些自适应方法应用于实际系统的限制。因此，从实际应用中，考虑具有简单控制器结构和鲁棒性的控制器，相对于不确定性非常重要。这项研究涉及基于包括MIMO系统的非线性系统的输出反馈的设计方案的综合，其中只有输出信号。特别是研究了以下主题。1）基于输出反馈的稳健自适应控制系统的设计，用于MIMO非线性系统。2）具有平行馈电补偿器的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，用于离散系统4）
