In previous work in [4], we had considered the application of a nonlinear coiitrol strategy based on neural networks to address the position control problein in such servomechanisms. The anuerse i ioii lmear coniroller usang neural iteiworks described there was shown to be capable of providing excellent closed-loop control for several classes of servomechanisms with fairly severe nonlinearities. The work in [4] also included experimental results for real-time control of a pilot-scale nonlinear position control system. However, the technique requires an accurate approximation to be provided by the neural network realisation of the nonlinear open-loop system. This typically requires a large number of hidden nodes for real-life syateiiis (refer to real-time experimental results in [4]), with the attendaiit disaclvantage that large training data frames and long training times are required. A further drawback of the controller of [4] is that it does not provide a built-in capability to adapt to changes in the system to be controlled.","PeriodicalId":170527,"journal":{"name":"Proceedings.

The primary design and mechanization tool is Integrated Systems Inc. software MATRIXx, utilizing the Robust Control Module, and implementation using the AC-100 Rapid Prototyping System. In addition, alternative robust control algorithms are developed using both the Rockwell Science Center developed Rho-Synthesis and The Mathworks Robust Control Toolbox with MATLAB. The design requires precision platform alignment to the gyro inertial reference with tracking errors less than one arcsecond in the presence of torque disturbances and sensor noise. Performance and stability robustness are required in the design to counteract large parameter variations that may occur in the actuator or in the the gimbal bearing friction. Figure 1 shows the stable platform (innermost gimbal) with the additional outer gimbals required for alignment about all three stable platform fixed axes. At present the development is focused upon implementing the prototyping hardware and controller for a single platform axis. The control designs presented here are H and Hinf robust control algorithms for Single Input Single Output (SIS0) control about the platform +z axis.","PeriodicalId":170527,"journal":{"name":"Proceedings.
