Abstract

The method of individual channel analysis and design (ICAD) is a neo-classical frequencydomain approach to analysis and design of multi-input multi-output control systems. In this paper the technique is applied to a two-input two-output nonlinear system involving two coupled tanks of liquid. The complete nonlinear model of the plant is presented and it is shown how the individual channel approach can provide useful insight for multivariable control system design based on linearised representations of the plant. Simulation investigations involving the nonlinear model have demonstrated that the overall performance of an ICAD-based control system design with proportional plus integral controllers satisfies a given set of performance specifications involving steady-state and transient requirements. Simulation results also show that this design provides good disturbance rejection and satisfactory robustness properties. The resulting control system has been implemented on the two-tank system and the paper includes experimental results.
