PERFORMANCE EVALUATION OF CONTROLLERS BASED ON COMPUTED TORQUE FOR ROBOT MANIPULATORS
摘要
Abstract
The paper compares the performance of five kinds of controllers based on computed torque with the problem of robot motion control: computed torque control with fixed gains, computed torque control with varying gains tuned via fuzzy approach, sectorial fuzzy controller, composite nonlinear feedback controller with saturation function and composite nonlinear feedback controller without saturation function. All the controllers are model-based methods and have the complete nonlinear dynamics compensation. The physical limitations are considered, such as actuator saturation and friction. The transient response and steady performance are compared among these control algorithms under the same desired trajectory. The simulation results show that the composite nonlinear feedback controller with saturation function has the best transient response, while the sectorial fuzzy controller has the best steady performance.关键词
