| Abstract |
To draw full advantage from a direct digital cascade control scheme by applying modern microprocessor technology established continuous control principles may be used as a guideline to be adapted to sampled-data control systems. The criteria of reference frequency response with closed-loop unity gain magnitude (UGM) approach are applied to find optimization rules for the parameters of discrete cancellation controllers. Performance effectiveness is increased by further programmed properties using compensation and observer techniques without additional hardware expenditures. Design objectives are to rapidly follow reference settings and rejecting disturbances effectively. The experimental results confirm the practicability of the strategy pursued and allow the conclusion that it may improve the performance of electrical drive systems with cascade structure. |
