摘要：A laboratory system for real-time robust control of multivariable analogue 4th order two input/two output plant is presented. The system consists of Spectrum Digital eZdspTMF28335 development kit with built in Texas Instruments TMS320F28335 Digital Signal Processor (DSP), digital to analogue signal converter, voltage divider, and a test analogue plant. A 16th order discrete-time -controller with sampling frequency of 100 Hz is implemented by using a DSP. The -controller designed ensures robust performance of the closed-loop system in presence of parametric uncertainty in two plant parameters. Frequency domain analysis of the discrete-time closed-loop system is performed. The implementation of highorder robust control law is facilitated by the usage of technology for automatic code generation. An appropriate software in MATLAB®/Simulink® environment is developed which is embedded in DSP by using the Simulink Coder®. Experimental and simulation results are presented which confirm that the control system achieves the prescribed performance.
