Abstract

Sliding mode controller theory is used to develop a unified perspective on the operation of hysteretic controllers (HCs) and ramp-comparison controllers (RCCs). It is shown that additional insight into the operation and tracking ability of the conventional controllers is possible by treating them as special cases of the sliding mode based controller (SMBC) and applying sliding mode control theory. This is accomplished by resisting the HC and the RCC in terms of their operation inside and outside a boundary layer. In particular, it was shown that, with the proper choice of parameters, the SMBC and the RCC differ solely in their region of nominal operation. Whereas the RCC is typically operated within its boundary layer (linear region), the SMBC is designed for operation both inside (linear region) and outside (switched region) its boundary layer. A SMBC was developed with a performance that is superior to the conventional HC and RCC controllers. The transition between nonlinear and linear control is handled quite naturally by the SMBC. The current controller analysis is performed on a DC motor.<>

迟滞和斜坡比较电流控制器的统一方法

滑模控制器理论被用来建立一个统一的观点对滞回控制器(hc)和斜坡比较控制器(rcc)的操作。结果表明，通过将传统控制器作为基于滑模的控制器(SMBC)的特殊情况并应用滑模控制理论，可以进一步了解传统控制器的运行和跟踪能力。这是通过抵抗HC和RCC在边界层内外的操作来实现的。特别是，研究表明，在适当选择参数的情况下，SMBC和RCC仅在其标称运行范围内不同。RCC通常在其边界层(线性区域)内运行，而SMBC设计用于在其边界层内(线性区域)和外(切换区域)运行。开发了一种性能优于传统HC和RCC控制器的SMBC。非线性和线性控制之间的过渡是由SMBC很自然地处理。对直流电机进行电流控制器分析
