五、内容简介：
The overhead crane is vital in handling payloads. It provides payload transportation services in rocket launch sites, automated assembly lines, shipping yards, warehouses, mining sites, and power plants. Despite the fact that many exciting techniques and findings for the control of overhead cranes have been published, advanced control strategy designs for these underactuated systems remain an open research area. A thorough literature review is presented in this research work, emphasizing the advantages, limitations, and problems of existing control strategies. Advanced control laws based on conventional and higher-order sliding mode controls and Takagi-Sugeno (T-S) parallel distributed compensation (PDC) control are developed to stabilize the systems and meet specific performance objectives. Some algorithms and methods exploited to achieve the specified control efficacy for these control methods included the neural network, fuzzy logic, prescribed performance function, T-S fuzzy PDC, linear matrix inequality formulations.
