Robust Controller Design Using RBF Networks - This approach leverages Radial Basis Function (RBF) networks to approximate arbitrary nonlinear relationships. The objective is to minimize the sum of squared errors, aligning with nonlinear Principal Component Analysis (PCA) goals. The nonlinear PCA model can be implemented using two separate RBF networks: one for nonlinear forward transformation and another for inverse transformation. Each RBF network is a three-layer feedforward architecture with radial basis functions as activation functions in the hidden layer. The first network maps high-dimensional data to a low-dimensional space (Figure 4), while the second network reconstructs the original high-dimensional data from the low-dimensional representation (Figure 5). Both networks require independent training to ensure optimal performance.

RBF networks face challenges in determining hidden layer node centers and basis width parameters; they possess unique optimal approximation properties without local minima. However, their Gaussian activation functions exhibit localized characteristics. We implement function approximation using fuzzy RBF networks, which effectively handle fuzzy data and uncertainty through integrated membership functions and rule-based reasoning mechanisms.
